NG Electronics manufactures common mode chokes, EMI filter chokes and noise suppression chokes at our ISO 9001:2015 certified plant in Pune. If your product is failing conducted emissions at CISPR 32 or CISPR 14, a correctly specified common mode choke is usually the fastest and cheapest route to compliance — and we build them to your impedance curve, not just to a catalogue number.

Our common mode choke range spans compact PCB common mode chokes from 250mA up to heavy ring core chokes rated 50A for three phase power line filtering. We wind on high permeability MnZn and nanocrystalline toroidal cores, using sectional, bifilar and split-winding techniques to hit the leakage inductance and inter-winding capacitance your filter design actually needs.

As an EMI filter component manufacturer working directly with Indian OEMs, we can move from a failed EMC test report to a validated sample in days rather than the weeks an import cycle would cost you.
