Highly-reliable and efficient power inductors for automotive applications

Now available from TTI Europe, TDK's CLF-NI-D series of rugged power inductors for use in automotive electronics feature high efficiency and reliability over a very wide temperature range extending from -55C to +150C and offer rated inductance values from 1µH to 470µH (E6 series). Measuring only 7.4mm x 7.0mm x 4.5mm, the CLF7045NI-D types are available for rated currents of 0.41A to 8.5A and offer DC resistance values ranging from 9mohm to 1.2ohm. The components are qualified to AEC-Q200. Due to TDK's advanced materials technology the devices 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 the products. As a result, the new power inductors are well suited to 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 7mm form factor complement the recently introduced 6mm square CLF6045NI-D types. TDK is already planning to further expand the CLF-NI-D series with 5mm, 10mm and 12.5mm square types in order to offer a broad lineup of power inductors that are suitable for a wide range of applications, says the company.
