Rugged magnetically shielded power inductors for VRM and VRD uses introduced by Coilcraft
CARY, Ill., 16 Dec. 2014. Coilcraft Inc. in Cary, Ill., is introducing the XAL15xx family of rugged, magnetically shielded power inductors for voltage regulator module (VRM) and voltage regulator-down (VRD) applications.
The power inductors come in two versions -- one providing saturation current ratings to 111 Amps and the other offering inductance values as high as 33 µH - delivering performance in a small package.
The XAL1510 Series offers a combination of high inductance values (to 33 µH) and current rating as high as 39.0 Amps, all in a package that measures 15.4 by 16.4 millimeters and has a maximum height of 11 millimeters.
For higher-current applications, the XAL1580 Series offers Isat ratings to 111 Amps, with a 15.2-by-16.2-millimeter footprint and maximum height of 8.2 millimeters. Both series offer very low DCR down to 0.70 mOhms.
They feature RoHS compliant tin-silver over copper terminations and offer a maximum reflow temperature of 260 degrees Celsius. 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.
