TDK launches wide frequency range wire-wound inductors for automotive power-over-coax applications

 Bild_w_background_en
  • Wide frequency range beyond 1 GHz to enable high impedance characteristics
  • Reduced footprint by minimizing the number of power-over-coax (PoC) filter inductors to one component
  • Suitable for high temperature environments; supports a wide operation range of -55 °C and +155 °C

TDK Corporation (TSE: 6762) has expanded its ADL4524VL series (4.5 x 2.4 x 2.6 mm – L x W x H) of wire-wound inductors for automotive power-over-coax (PoC). Mass production of these components began in July 2025.

With automotive PoC technology, a single coaxial cable can simultaneously carry both power and data. PoC is widely used in automotive camera systems as ADAS for safe driving has become more widespread. Using a single coaxial cable for power and signal lowers the vehicle’s weight by reducing cabling, which in turn helps to improve fuel and power consumption. Simplified cabling within the vehicle also allows for a more effective use of the space.

The PoC system requires a filter incorporating multiple inductors to separate power from the data signal before processing effectively. This product enables high impedance at a wide frequency range from 10 MHz to 1 GHz with its proprietary materials and structural design innovation. This reduces the number of inductors used to save space. By covering a wide frequency range, this product can handle applications with fewer inductors. For example, where conventional solutions might require three inductors, this solution requires only one. The inductor ensures high reliability with an upper operation temperature range limit of +155 °C.

Looking ahead, TDK is committed to developing inductors for automotive PoC applications by pursuing optimized design by refining multilayer, wire-wound, and thin-film technologies to address market needs. TDK will expand its lineup of products to improve the quality of PoC transmission signals.

TDK announces its decision to implement a public buyout offer, followed by a mandatory squeeze-out on Tronic’s Microsystems shares

  • TDK’s wholly owned subsidiary TDK Electronics, a leading German manufacturer of electronic components, plans to launch a public takeover offer followed by a mandatory squeeze-out for Tronic’s shares. 

  • TDK Electronics AG, main shareholder of Tronic’s, owns 87.34% of Tronic’s shares. The concert formed between TDK Electronics AG and Thales AVS France SAS owns 97.44% of the Tronic’s shares. 

  • The price of the tender offer, that will be filed to the AMF, is 5.56 Euros per Tronic’s share. 

    TDK Corporation (“TDK”, TSE: 6762) announced today that TDK’s wholly owned subsidiary TDK Electronics AG, a leading manufacturer of electronic components, modules and systems based in Munich, Germany, has decided to implement a public buyout offer followed by a mandatory squeeze-out (the “Offer”) for Tronic’s Microsystems SA (“Tronic’s”, ISIN:FR0004175099 ALTRO) shares. TDK Electronics AG, main shareholder of Tronic’s, owns 87.34% of Tronic’s shares. The concert formed between TDK Electronics AG and Thales AVS France SAS owns 97.44% of the Tronic’s shares. 

    The price of the tender offer, that will be filed to the AMF, is 5.56 Euros per Tronic’s share.

    Context of the Offer 

    The Offer is part of a move to simplify Tronic’s' capital structure by acquiring the remaining capital not currently held by TDK Electronics AG and Thales AVS, France SAS (2.56% of the capital of Tronic’s), for which it is being specified that TDK Electronics AG will act as sole initiator, and is in line with Tronic’s’ strategy, which does not require it to remain listed on the Euronext Growth® market in Paris, particularly given the very low liquidity of the stock. The Offer also aims to reduce the costs associated with the listing. As a reminder, TDK Electronics AG has been financing Tronic’s these last years and expects to recapitalize Tronic’s with up to 7,000,000 Euros before March 31, 2026, as the equity of Tronic’s is lower than half of its share capital since 2023. 

    TDK Electronics AG is therefore offering Tronic’s shareholders who tender their shares to the Offer the opportunity to obtain immediate liquidity for their entire stake at a price of 5.56 Euros per share. 

    As Tronic's is unable to set up an ad hoc committee as referred to in III of Article 261-1 of the AMF General Regulation, it will shortly submit to the AMF the identity of the independent appraiser it intends to appoint, in accordance with Article 261-1-1-I of the General Regulation. 

    Additional information related to the transaction  

    The public will be informed of the filing of the draft documents relating to the Offer, which will be published by TDK Electronics AG and Tronic's during the third quarter of 2025. In accordance with French law, the documentation relating to the Offer will include the draft note of information, prepared by TDK, setting out the terms and conditions of the Offer, as well as the draft note in response, prepared by Tronic’s, including the independent appraiser’s report and the reasoned opinion of the supervisory board, and will be subject to review by the AMF.

TDK introduces automotive power-over-coax inductor for filters with industry-leading simplicity and efficiency

 Bild_w_background_en

TDK Corporation (TSE:6762) launches the ADL8030VA, a high-performance inductor designed specifically for power-over-coaxial (PoC) applications. Due to its high impedance over a wide frequency range, this component streamlines the PoC filter design by requiring only one single component instead of the conventional approach with two or more inductors. This significantly reduces complexity and cost in advanced driver-assistance systems (ADAS) and other automotive electronics, where space efficiency and reliability are critical. With the ADL8030VA, TDK is once again driving mobility transformation toward a more connected and safe future.

In standard configurations, ADAS sensors like automotive cameras require two separate lines: one power line connected to the battery and a signal line connected to the electronic control unit (ECU). However, with PoC technology, a single coaxial cable can simultaneously carry both power and data, simplifying and reducing the wire harness.

The 7.8 x 2.7 x 2.7 mm (L x W x H) small ADL8030VA series offers inductance values from 10 µH to 100 µH with a rated current range of up to 0.82 A, ensuring robust performance from -55 °C to +155 °C across a wide frequency spectrum. Its low DC resistance of less than 0.5 Ω for the types with 22 µH or less minimizes power losses, enhancing overall energy efficiency. Its compact design is engineered with a ferrite core, enamel copper wire welded to the terminals, and flame-retardant molding. It offers high mechanical stability and meets AEC-Q200 qualification standards, ensuring durability under harsh automotive conditions.

Awards from automotive customers for excellent cooperation and on-time delivery

 Teaser_LG

In China, Sales received two awards from automotive suppliers. TDK Sales South China won the “Excellent Business Cooperation Award” from Desay SV, a manufacturer of electronics, antenna, and software solutions. TDK Sales North China received the “Quality Delivery Excellence Award” from the Japanese-Chinese joint venture TFDA (TianJin Fawer Denso Air-Conditioner), that produces air conditioning systems.

Desay SV the award to Makoto Kondo (Senior Vice President TDK Greater China Sales Division and Block General Manager TDK South China) and Kelby Yang (Sales Director TDK South China Automotive Team) at its partner conference. Desay SV recognized TDK's delivery performance for inductors manufactured at the Xiamen site in China. “This award is not only a confirmation of TDK's performance to date, but also an expectation for future cooperation,” said Kondo. He pointed out that TDK had to manage supply shortages due to high demand for xEV and ADAS in the Chinese market. Thanks to close cooperation between the Business Group and Sales, it was possible to increase capacity. “I am very happy that we are now able to meet the customer's expectations and have received this award today,” Kondo continued.

The Denso joint venture TFDA (TianJin Fawer Denso Air-Conditioner) presented TDK Sales North China with the Quality Delivery Excellence Award. Sayou Tomoki, Director of TDK ECBC Sales Group North China, accepted the award on behalf of TDK.

TFDA manufactures air conditioning systems for motor vehicles and sources temperature sensors for this purpose from its site in Batam, Indonesia. This is the second award TFDA has given to TDK Sales North China, following the “Best Supplier” award in 2020.

TDK offers 3-terminal filters for automotive applications at higher voltages and higher capacitances

 Bild_w_background_en
  • New 35-V products with 0.22 µF in 1005 size and 10-V products with 4.7 µF in 2012 size for automotive applications added to the lineup
  • Contributes to the reduction of component count and the miniaturization of sets as well as reduces voltage fluctuation and high-frequency noise
  • Qualified based on AEC-Q200

TDK Corporation (TSE: 6762) has expanded its YFF series of 3-terminal filters for automotive applications to include higher voltages up to 35 V and higher capacitances up to 4.7 µF. Such components are used to suppress voltage variation and high-frequency noise, which can cause system malfunctions. Mass production of the product series began in June 2025.

With the miniaturization of automotive electronic systems, there is an increasing demand for measures to prevent system malfunctions. Usually, numerous capacitors are employed in such applications. On the other hand, the number of components must be reduced due to the miniaturization of these systems. To address these challenges, 3-terminal filters, characterized by a low ESL (equivalent series inductance), are gaining significant demand.

By optimizing the material selection and product design, the new products feature significantly higher withstand voltage, ranging now from 6.3 V to 35 V, and considerably higher capacitance, ranging now from 0.47 μF to 4.7 μF. The 35-V product with an insertion loss of 40 dB (4 MHz to 2 GHz) can be used for a broader range of power lines, including both input and output of power-supply systems, while the 4.7 μF product with an insertion loss of 30 dB (300 kHz to 3 GHz) is more effective as input capacitors than conventional products in reducing voltage fluctuation and countering high-frequency noise. Moreover, depending on set usage conditions, it is possible to halve the component count required to suppress voltage fluctuations to the same extent from the MLCC.
