Lineup of rugged power inductors for automotive electronics applications expanded
- Wide temperature range from -55°C to +150°C
- Improved mechanical strength and high reliability
- Qualified to AEC-Q200
TDK Corporation has expanded its CLF-NI-D series of rugged power inductors for use in automotive electronics. The new CLF7045NI-D wirewound SMD power inductors feature high efficiency and reliability over a very wide temperature range extending from -55 °C to +150 °C and offer rated inductance values from 1.0 μH to 470 μH (E6 series). Measuring in at 7.4 mm x 7.0 mm x 4.5 mm, the CLF7045NI-D types are available for rated currents of 0.41 A to 8.5 A and offer DC resistance values ranging from 9 mΩ to 1.20 Ω. Mass production will be launched in August 2015.
The new products are qualified to AEC-Q200. Thanks to TDK's advanced materials technology the new components feature outstanding heat resistance. A new bonding process for the terminals enables a solderless structural design that features improved mechanical strength. The fully automated manufacturing process ensures the high reliability and quality of these components. As a result, the new inductors are very well suited for applications in demanding automotive environments such as the power supply circuits of engine control modules (ECM) and ECUs for airbags, ABS, and headlights.
The new CLF7045NI-D types with a 7 mm form factor complement the recently introduced 6 mm square CLF6045NI-D types. In the future, TDK will further expand the CLF-NI-D series with 5 mm, 10 mm and 12.5 mm square types in order to offer a broad lineup of power inductors that are suitable for a wide range of applications.
