Coilcraft Introduces AEC-Q200 Grade 1 Molded Power Inductors at APEC 2019

March 13, 2019 by Scott McMahan

Coilcraft will introduce its new XGL4020 Series of molded power inductors at the Applied Power Electronics Conference (APEC), March 17-21 in Anaheim, CA. According to the company, the series of molded power inductors features the industry's lowest dc losses and extremely low AC losses for a wide range of dc-dc converters (from hundreds kHz up to 5+MHz). Additional performance enhancements include a wider range of inductance values and improved Irms current ratings.

The XGL4020 is available in twelve inductance values from 0.33µH to 8.2µH, with current ratings up to 15.2A and soft saturation characteristics. Its dc resistance is up to 45% lower than Coilcraft's next lowest soft-saturation products. Lower DCR and higher Irms also allow the XGL4020 to operate much cooler than other components.

XGL4020 Series inductors are qualified to AEC-Q200 Grade 1 standards (-40° to +125°C ambient) with a maximum part temperature of +165°C and exhibit no thermal aging issues, making them suitable for automotive and other harsh-environment applications. They feature RoHS-compliant, tin-silver-over-copper terminations and are halogen-free. Their composite construction also minimizes audible buzzing.
