Shielded Power Inductors Withstand High Temps

May 13, 2020
A wide range of inductance values, high current ratings, and high temperature ratings make these inductors useful in automotive applications.

Coilcraft’s new XAL7050 series of high-temperature/low-DCR power inductors are now available with inductance values from 22 to 47 µH and current ratings as high as 5.5 A. The new inductors measure 7.2 x 7.5 x 5.0 mm and are fabricated into a rugged composite that provides magnetic shielding and minimizes audible buzzing. They are also qualified to AEC-Q200 Grade 1 (−40°C to +125°C) standards and exhibit no thermal aging issues.

The tin-silver (96.5/3.5) over copper terminations are RoHS-compliant and have a maximum reflow temperature of 260°C. Optionally, COTS-Plus tin-silver-copper and tin-lead terminations are available.

The XAL7050 devices are able to withstand high current spikes due to soft saturation characteristics and have a calculated MTBF of 26,315,789 hours. Parts are in stock and currently available for order; contact Coilcraft for free evaluation samples and complete technical specifications.
