Semi-Shielded inductors SQH SERIES(2~8mm)

Coilmaster's SQH series - surface mount power inductors - featuring magnetic epoxy shielding as a lower cost alternative to conventional ferrite shielded inductors. By replacing the traditional ferrite shield with a magnetic epoxy resin, we are able to significantly reduce both material and labor costs, as well as improve production lead times.

With regards to performance, the coupling factor (K) of the magnetic epoxy inductors falls somewhere between that of ferrite shielded and unshielded inductors. These new series of inductors are offered with the same or similar overall dimensions and footprint as their ferrite shielded and unshielded counterparts and so provide a nice alternative, bridging the gap between the two.

Ideal applications for these lower cost inductors include DC/DC converter, power supply, computer, LED lighting, and various industrial and consumer electronics products.
