Coilcraft has launched a range of high-temperature power inductors is available with inductance values from 22 to 47 µH and current ratings as high as 5.5 Amps,.

The XAL7050 Series of power inductors features RoHS-compliant tin-silver (96.5/3.5) over copper terminations and offers a maximum reflow temperature of 260°C. COTS Plus tin-silver-copper and tin-lead terminations are also available.

For lower inductance values, Coilcraft offers a lower-profile companion, the XAL7030 power inductor, with an identical footprint and inductance range of 0.16 to 10µH. The XAL7050 measures just 7.2x7.5x5.0mm and features a rugged, composite construction that provides magnetic shielding and minimizes audible buzzing. It is qualified to AEC-Q200 Grade 1 (−40°C to +125°C) standards and exhibits no thermal ageing issues, making it suitable for automotive and other harsh-environment applications. Soft saturation characteristics allow the XAL7050 to withstand high current spikes.
