High-Current Inductors for High-Frequency Applications

Coilcraft's new SLR Family of high-current, shielded power inductors is offered with current ratings up to 100A and inductance values from 85- to 370-nH, making it suitable for high-frequency applications such as multi-phase VRM/VRD/EVRD regulators, Intel™ IMVP compatible systems, and GPUs/video graphic cards. The inductors also feature a tight DCR tolerance (±5.4% to ±10%) for lossless, inductor DCR-based current sensing.

The SLR Family comprises five product series: the SLR1050, SLR1065, SLR1070, SLR1075 and SLR1190. The compact SLR1050 Series offers an inductance range of 85- to 220-nH and current ratings up to 86A in a 10.2 X 7.0 X 4.95 mm package. It is offered in three DCR versions for optimal efficiency and accuracy.

The SLR1190 offers the highest current ratings in the family – up to 100 Amps – and an inductance range of 150- to 370-nH. It measures 11.2 X 10.3 X 9.0 mm. All SLR Family inductors feature RoHS compliant, matte tin over nickel over copper terminations and offer a maximum reflow temperature of 260 degrees C.
