Welcome at to Coil Winding 2019! The Coil Winding, Insulation and Electrical Manufacturing Exhibition (CWIEME) in Berlin is the world’s leading exhibition for these technologies. We are presenting the comprehensive portfolio of EPCOS and TDK inductors, ferrite cores and accessories, and high-performance TDK magnets for all electronics sectors. Convince yourself about our innovative products and solutions. We’re looking forward to your visit!
Low losses at high frequencies
The MnZn-based PC200 ferrite material is characterized by low losses at high frequencies. It was developed specifically for power supplies and frequency converters that operate with fast-switching power semiconductors on a GaN basis. The new material is optimized for a frequency range from 700 kHz to 4 MHz. Its maximum transmissible power is reached at a switching frequency of 1.8 MHz to 2 MHz and an operating temperature of 100 °C. The ferrite material’s Curie temperature is in excess of 250 °C.
The PC200 ferrite material is particularly suitable for transformers based on ring core or planar topologies. The new material is available in ER, EFD, ELP, EQ, I and RM cores. The outstanding properties of this material will enable considerably more compact power supplies to be designed in future. At the same time, its efficiency is improved due to the low losses of the ferrite material, which is why the use of PC200 contributes to significantly greater energy savings.
SMT high-current chokes with a compact design
The portfolio of EPCOS ERU SMT power inductors has been expanded with the ERU16 choke series that comprises ten different types. The inductance values of the new B82559*A016 series extend from 1.0 µH to 30 µH and their saturation currents range from 9.2 A DC to 37 A DC. The outstanding feature of these new power inductors is their compact design: With a footprint of just 17.3 mm x 18.7 mm, they have low insertion heights of 7.55 mm (1.0 µH) to 10.95 mm (30 µH), depending on the type. This low-profile design is based on a flat rectangular helical winding technology which results in lower losses.
The DC resistances are between 1.05 mΩ and 15.35 mΩ. With the new ERU16 types TDK is expanding its broad spectrum of ERU SMT power inductors, which include the existing ERU13, ERU19, ERU20 and ERU25 series. The new series of high-current chokes is designed for operating temperatures of between -40 °C and +150 °C. Its additional third soldering pad results in high mechanical stability on the PCB. They can be used as output and storage chokes in a wide variety of power supply topologies. These include point-of-load (POL) converters, DC-DC converters, high-current switch-mode power supplies, solar converters and xEV applications. The components of the new series are RoHS-compatible and qualified to AEC-Q200.
