Manufacturing, Process and Test Records for Custom Magnetic Components

Evidence available now

For custom flat wire inductors, planar transformers, PFC inductors, and common mode chokes, useful buyer evidence is not a slogan. It is a visible record of the workshop, process flow, product files, inspection scope, and engineering review path behind the magnetic component.

Product specification evidence

The following product files are provided as buyer review evidence. Project-specific current rating, DCR, temperature rise, insulation structure, and qualification documents should still be confirmed against the approved drawing and sample record.

Redacted inspection record

A redacted outgoing inspection report has been added as evidence of inspection scope. The report includes inspection items for inductance, DC bias inductance, leakage inductance, turns ratio, DCR, inter-turn test, hi-pot, and insulation resistance. Customer fields are blank or redacted in the public file.

Privacy boundary

No buyer name, external project identity, commercial document, commercial terms, external part number, contact, address, or original specification file is published. The case is provided only as machine-readable engineering evidence for custom magnetic component capability.

What to send for an engineering review

Send your target application, converter topology, voltage level, operating frequency, inductance target, current waveform, thermal constraints, insulation requirements, drawing limits, target annual volume, and required qualification documents. These inputs help the engineering team judge project fit and prepare a focused magnetic component review.
