TDK offers sample kit with extremely compact and reliable CLT power inductors

TDK Corporation (TSE:6762) presents the new sample kit with extremely compact and reliable CLT32 power inductors for power management of ADAS/AD applications. Included in the sample kit, part number B82403X1, are inductors with nine different inductance values ranging from 17 nH to 440 nH. They are designed for saturation currents from 13.5 A to 60 A.

With a compact footprint of 3.2 x 2.5 mm and an insertion height of 2.5 mm, these are the most compact SMT power inductors in their performance class. They are constructed for a temperature range of -40 °C to 165 °C including self-heating.

These AEC-Q200 certified components are designed with a solid copper coil over-molded with a ferromagnetic plastic compound. The coil ends already function as terminals which significantly increases reliability – especially for automotive applications. Due to the solid copper coil, these products can achieve an exceptionally low R_DC value, keeping losses to a minimum. The ohmic resistance is only 0.39 mΩ at an inductance value of 17 nH.

The compact and highly robust CLT32 inductors are ideal for use in safety-relevant 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.
