NG Electronics is an ISO 9001:2015 certified toroidal power inductor manufacturer based in Pune, Maharashtra, supplying high current toroidal inductors, toroidal chokes and toroidal coils to OEMs, EMS partners and design houses across India. Every toroidal core inductor we ship is wound in-house, tested in-house and traceable to a batch record — nothing is outsourced and nothing is rebadged.

Our standard toroidal power inductor range covers 10µH to 10mH with current ratings up to 25A, wound on iron powder and ferrite toroidal cores. Because the magnetic flux stays contained inside the closed ring geometry, a toroidal coil radiates far less stray EMI than an equivalent bobbin or drum wound part — which is exactly why designers of SMPS, solar inverters, EV chargers and UPS systems specify toroidal inductors when board space is tight and EMC compliance is non-negotiable.

Whether you need 100 pieces of a catalogue part or a fully custom toroidal inductor built to your inductance, saturation current and temperature rise targets, our engineering team will work from your specification to a validated sample, typically within 7 to 10 working days.
