On the floor
Wound by hand. Held to print.
The photographs are parts on our bench in Chikhali, Pune — and every build is checked against your drawing from the first sample to the last lot.
- Low-loss windingsTransfer efficiencyTight turns, correct core grade and controlled DCR so magnetics move power instead of heat — critical for SMPS, inverters and compact drives.
- 98%+
- Held to printYears windingSince 2017 in Pune we have wound ferrite transformers and inductors for harsh duty cycles — insulation, taping and geometry stay on the drawing.
- 8+
- Custom to envelopeBuild-to-printSend inductance, current, frequency and mechanical envelope. We iterate the winding and deliver a sample you can drop into the board.

How we work
From print to copper on the bobbin.
Four steps, one engineer on your part throughout — and you approve a sample before you commit volume.
- 01
Send the print
L, DCR, current, frequency, core preference and envelope — or the board problem you are solving. Datasheets welcome.
→Your specification
- 02
Winding review
We confirm core grade, turns, insulation and creepage, then return a build proposal.

Sample sign-off
A wound sample for electrical and fit checks. We iterate until inductance and envelope match the drawing.
→First-article sample

Volume production
Repeat builds to the approved standard — typically 2–3 weeks, faster when the line needs it.
