NG Electronics manufactures drum core inductors and drum core coils at our ISO 9001:2015 certified facility in Pune. Wound on ferrite drum cores in shielded and unshielded constructions, these are the compact, cost-effective power inductors that go straight onto a PCB — in SMD, radial and axial through-hole formats to suit whatever assembly process you run.

A drum core inductor is the practical choice when you need decent current handling in a small footprint at a sensible price. The exposed bobbin geometry makes it fast and repeatable to wind, which keeps unit cost down; adding a ferrite sleeve or resin shield around the winding contains the flux and brings EMI performance close to that of a toroid.

Our range spans low current signal chokes through to high current drum core inductors of several amps, and we supply both catalogue parts and made-to-order builds against your inductance, DCR and footprint requirements.
