Magnetically Shielded Power Inductors in High Inductance, High Isat Versions

Nov10_CoilcraftCoilcraft’s XAL15xx Family of rugged, magnetically-shielded power inductors are offered in two versions – one providing saturation current ratings up to 111 amps and the other offering inductance values as high as 33 µH – delivering the highest levels of performance in the smallest possible space.

The XAL1510 series offers a unique combination of high inductance values (up to 33 µH) and current rating as high as 39.0 amps, all in a compact package that measures 15.4 by 16.4 mm and has a maximum height of 11.0 mm. For even higher current applications, the XAL1580 series offers Isat ratings up to 111 amps, with a 15.2 by 16.2 mm footprint and maximum height of 8.2 mm.

Both series offer very low DCR, down to 0.70 mOhms for the XAL1580, and their soft saturation characteristics make them well suited for VRM/VRD applications. They feature RoHS compliant tin-silver (96.5/3.5) over copper terminations and offer a maximum reflow temperature of 260°C. And like all Coilcraft XAL/XFL inductors, the XAL1510 and XAL1580 series feature a proprietary composite core that is not subject to thermal aging issues associated with other iron powder core inductors.

As with all Coilcraft parts, free evaluation samples and complete technical specifications are available online at
