TDK Corporation has expanded its CLF-NI-D series of rugged power inductors for use in automotive electronics. The CLF7045NI-D wirewound SMD power inductors feature high efficiency and reliability over a temperature range of -55 to +150°C and offer rated inductance values from 1.0 to 470μH (E6 series). The CLF7045NI-D types are available for rated currents of 0.41 to 8.5A and offer DC resistance values ranging from 9mΩ to 1.20Ω.
Measuring in at 7.4x7.0x4.5mm, the products are qualified to AEC-Q200. Thanks to TDK's advanced materials technology the components feature outstanding heat resistance. A bonding process for the terminals enables a solderless structural design that features improved mechanical strength.
TDK's automated manufacturing process ensures consistency, reliability and quality. As a result, the inductors are suited for applications in demanding automotive environments such as the power supply circuits of Engine Control Modules (ECMs) and ECUs for airbags, ABS, and headlights.
The CLF7045NI-D types with a 7mm form factor complement the recently introduced 6mm square CLF6045NI-D types. In the future, TDK will further expand the CLF-NI-D series with 5, 10 and 12.5mm 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.
