Highly compact rugged inductor for ADAS/AD automotive applications

For use in rugged automotive applications passive component maker TDK Has made available a extremely compact 3.2 x 2.5 x2.5 mm size inductor series called  CLT32. Available in the inductance range of 17 nano Henries (nH) to 440 nH with ability withstand 13.5 A to 60 A saturation currents. Claimed as most compact SMT power inductors in their performance class these are designed to withstand temperature range of -40 °C to 165 °C including self-heating.

AEC-Q200 certified inductors feature  solid copper coil over-molded with a ferromagnetic plastic compound. The coil ends are made to work as terminals ensuring higher reliability  for automotive applications. The solid copper coil ensures low RDC value, where the ohmic resistance is only 0.39 milli ohms at an inductance value of 17 nH.

CLT32 inductors are suggested for safety critical automotive applications in ADAS/AD. High-performance processors used in these fields require currents in the double-digit ampere range. Power Management ICs (PMICs) are used as power supplies that provide these high currents. Here, power inductors for stabilization are key components at the outputs. The CLT32 series is designed for switching frequencies of up to 10 MHz and already meets future requirements placed on DC/DC converters with high clock rates, explains TDK.

These inductors are  suitable for switching frequencies up to 10 MHz
