Custom Wound Inductors

An OEM inductor manufacturer for repeat production

Equipment makers and EMS companies need more from a magnetics vendor than a good sample. The part has to drop onto an existing footprint, arrive when the build is scheduled and measure the same in the twentieth batch as in the first. NG Electronics works as an OEM inductor manufacturer on those terms, winding and testing custom inductors in Pune for products that are already in production or about to be.

Most enquiries start from one of three situations. A new design needs an inductor that no catalogue offers. An approved part has gone obsolete or its lead time has become unworkable, and a second source is needed. Or an imported component is to be localised. In each case we work from your drawing, datasheet or a physical sample, and reproduce the mechanical and electrical values that matter to the circuit.

As a custom wound inductor supplier we use ferrite, iron powder, MPP, Sendust, High Flux, nanocrystalline and air cores, in through-hole, SMD, chassis-mount and flying-lead formats. That breadth lets one vendor cover the storage chokes, filter inductors and sensing coils on a bill of materials. Our team of over 50 handles work from first prototypes through to volume production.

  • Parts matched to existing pad layouts, pin pitch and height limits
  • Second-source equivalents for discontinued or long lead time catalogue parts
  • Batch records linking each lot to raw material and production date
  • Test certificate supplied with the order on request

Specifications

Manufacturing scope for OEM orders

Custom parts are defined by your drawing, so electrical limits are agreed per design. This table summarises what we can build and how orders are handled.

Inductance and currentSpecified per design
Core materialsFerrite, iron powder, MPP, Sendust, High Flux, nanocrystalline, air core
Mounting formatsThrough-hole, SMD, chassis and flying-lead
QuantitiesPrototypes to volume production
Production MOQTypically 100 to 1,000 pieces for custom parts
QuotationTechnical quotation within 24 working hours of receiving the specification
SamplesFree sample for lab approval; typically within 7 to 10 working days
Testing100% electrical test: inductance, DCR, Q factor, saturation current, hipot
ComplianceRoHS and REACH compliant materials; certificate copies available on request

For a replacement part, the original datasheet plus one physical sample is the fastest route to an accurate equivalent.

Design guide

How OEM supply and second sourcing work

Replacing a catalogue inductor is more than matching the inductance printed on the datasheet. Two parts with the same nominal value can differ in how inductance falls with DC bias, in core loss at the switching frequency and in self-resonant frequency, because those depend on core material and winding construction. An equivalent should therefore be approved in the actual circuit, with temperature rise and waveforms compared against the original, before it is added to the approved vendor list.

Vendor approval usually needs paperwork alongside the sample. We can provide a copy of our quality certificate, RoHS and REACH certificate copies on request, and test results for the samples submitted. For running production, share your expected release schedule at the quotation stage so that material and winding capacity can be planned against it. Each batch is recorded, so a field query can be traced to its lot.

  1. Share the specificationSend the drawing, datasheet or a sample part, with annual volume and batch size. Mark which dimensions and electrical values are critical.
  2. Technical quotationWithin 24 working hours you receive a quotation stating core, wire, construction and any deviation we suggest from the original.
  3. Sample approvalA free sample is wound for your lab. Fit it to the board, run your qualification tests and return any changes needed.
  4. Production with full testingApproved parts are built to the frozen specification, and every unit is electrically tested before packing.
  5. Delivery with recordsBatches ship from Pune with a test certificate where requested, and the batch record is retained for traceability.

About NG Electronics

Why OEM buyers approve NG Electronics as a vendor

Purchase teams look for a custom inductor manufacturer in India that can be audited, reached quickly and held to a specification. NG Electronics is ISO 9001:2015 certified, and all winding and testing is done in our own facility at Chimbli, Pune, not subcontracted. Test equipment includes LCR testers, impulse testers, insulation breakdown testers and power analysers, so the measurements on a test certificate are made in-house.

As an inductor OEM supplier we keep order sizes practical. About 10 pieces are enough for an R&D build, and production lots for custom parts typically begin at 100 to 1,000 pieces. Engineering support is free against firm production intent, which suits a custom power inductor manufacturer relationship that is meant to last through the life of your product. We deliver across India and welcome overseas enquiries.

Frequently Asked Questions

Answers about OEM inductor manufacturer from NG Electronics, an ISO 9001:2015 certified company

A drawing or datasheet showing inductance and tolerance, current, DCR limit, operating frequency, dimensions and termination details, plus the expected annual quantity. If no drawing exists, a physical sample and a description of the circuit are enough to start. A technical quotation follows within 24 working hours.

In most cases, yes. We measure or read off the key values, choose a comparable core material and wind an equivalent that fits the same footprint. Because bias and loss behaviour vary between core materials, the part should be validated in your circuit. A free sample is provided for that approval.

Once a sample is approved, the core, wire and winding details are frozen as the build specification. Every unit in every batch is tested for inductance, DCR, Q factor, saturation current and hipot. Batch records identify the raw material and production date, so any variation can be investigated.

We can share a copy of our ISO 9001:2015 certificate, copies of RoHS and REACH certificates on request, and a test certificate with supplied parts. Batch records showing raw material and production date support any traceability questions raised during approval.

Yes. We supply against the product owner's approved drawing whether the order comes from the OEM or from the EMS company building the board. SMD parts can be packed on tape and reel where the line requires it, and delivery batches can be planned around the build schedule you share.

The minimum is flexible. About 10 pieces is workable for R&D, and single-piece prototypes are possible for custom designs. Production orders for custom parts typically start at 100 to 1,000 pieces. Custom samples are typically ready in 7 to 10 working days, and production lead time is confirmed on the quotation.
