Low-loss Power Inductors Ride High-Frequency Applications

Coilcraft’s XEL50xx Family of high-performance, molded power inductors boast exceptionally low dc resistance and ultra-low ac losses, improving power converter efficiency at frequencies from 2 MHz 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 XEL50xx inductors measure 5.28 mm x 5.48 mm with a maximum height of 3.2 mm.

 

Two models are available: 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 39A. The XEL5030 has 10 values from 0.13 to 4.7 µH and current ratings up to 44A. All models offer soft saturation characteristics to withstand high current spikes and have no thermal aging issues.

 

Additionally, the 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.
