Rugged power inductors for automotive electronics operate from 55C to +150C

TDK's CLF-NI-D Series of rugged power inductors for use automotive applications are now available from TTI Europe. The CLF7045NI-D wirewound SMD power inductors 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 just 7.4mm x 7mm x 4.5mm, the compact CLF7045NI-D types are available for rated currents of 0.41A to 8.5A and offer DC resistance values ranging from 9mohm to 1.20ohm. The new products are qualified to AEC-Q200 and due to TDK's advanced materials technology feature high heat resistance. A new bonding process for the terminals enables a solderless structural design with improved mechanical strength. The inductors are particularly suitable for applications in demanding automotive environments such as the power supply circuits of engine control modules (ECM) and ECUs for airbags, ABS, and headlights.
