Metal composite inductors offer reliability in automotive power applications

April 3, 2025

The ETQPxMxxxKVx power choke coils from Panasonic Industry provide a range of options for case size and inductance, giving designers flexibility to meet the requirements in drive and converter circuits.

Panasonic Industry power choke coils with a metal composite construction are intended for use in automotive systems, which benefit from the superior robustness and high reliability.

 

These inductors, which are orderable with ETQPxMxxxKVx part numbers, are particularly well suited to functions including:

  • Noise filtering in drive circuits that are exposed to high temperatures and high peak currents
  • Dc-dc converters operating in either boost or buck mode

Supplied at an attractive price, these Panasonic Industry chokes benefit from metal composite technology which offers valuable characteristics such as non-saturation behavior, low losses, and high stability over a wide temperature range.

 

The ETQPxMxxxKVx inductors offer design engineers a wide choice of product options. Case sizes range from 5 mm x 5 mm to 12 mm x 12 mm. Inductance values range from 0.33 μH to 100 μH.
