TDK Corp. has expanded its line of CLF-NI-D rugged power inductors for use in automotive electronics. The new CLF7045NI-D wire-wound SMD power inductors feature high efficiency and reliability over a 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 mW to 1.20 W.
The new products are qualified to AEC-Q200. Due to TDK's advanced materials technology, the new components feature high heat resistance. A new bonding process for the terminals enables a solderless structural design that features improved mechanical strength. The new inductors are 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. Mass production will be launched in August 2015.
