CLT32 Power Inductors

CLT32 Power Inductors

Tiny Giants for ADAS/AD Systems

ADAS and AD systems place very high demands on the reliability of the components. That’s why TDK has developed the CLT32 product series for inductors used in power management units. This innovative and extremely compact series is setting new standards with regard to reliability, miniaturization and electrical parameters.

A compact footprint of 3.2 mm x 2.5 mm and an insertion height of 2.5 mm makes these SMT power inductors extremely compact. They are designed for a temperature range from -40°C to +165°C including self-heating.
