Coilcraft Releases Ultra Low-loss Power Inductors Series for High-frequency Applications

Coilcraft has released a new family of high-performance, molded power inductors that offer exceptionally low DC resistance and ultra-low AC losses. The XEL50xx series greatly improves the power converter efficiency at high frequencies (2 to 5+ MHz) and high ripple current.

The use of high switching frequencies or high ripple current allows a corresponding lower inductance value, which results in a physically smaller part for the same electrical specs. The inductors measure just 5.28 x 5.48 mm with a maximum height of 3.2 mm.

It is currently available in two models, the XEL5020 and XEL5030. A third model, the XEL5050 is expected late Q2 2018. The XEL5020 is available in six inductance values from 0.10 to 1.0 µH, with current ratings up to 39 amps, while, the XEL5030 has 10 values from 0.13 to 4.7 µH and current ratings up to 44 amps. All models offer soft saturation characteristics to withstand high current spikes and have no thermal aging issues.

The XEL50xx family of inductors are qualified to AEC-Q200 Grade 1 standards (-40° to +125°C ambient) with a maximum part temperature of +165°C, 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.
