Tell us what you need built

Custom windings, modified standard parts, and new designs. Send the specification you have — we come back within 48 hours with a part number or a proposal, pricing, and a two weeks lead time.

Custom is normal business here

The factory builds to order, so a modified part is not a favour and a new wind is not a special project — it is the same production line, quoted the same way. Most of what a design needs changed is a winding detail rather than a different supplier.

What we change

  • Turns ratio
  • Voltage
  • Core size
  • Mounting
  • Terminations
  • Potting
  • Enclosure
  • Approvals
Lead time
Samples in about two weeks once the specification is agreed, and two weeks on production orders after that.
Minimum quantities
Depend on the part, the core, and the winding. Your quote states the minimum for the part we propose.
Where it is built
Aslan Elektronik's own factory, manufacturing magnetics since 1986.

1. Contact information

2. Project details

What the part is for and how many you need. A best guess on volume is more useful to us than a blank.

This decides which technical fields appear in section 3. Pick the closest match if you are between two.

Filled in for you if you arrived from a part page. Leave it blank if you are starting from a specification rather than a part number.

Approvals or standards requiredoptional

Worth telling us now — an approval added after the design is fixed can mean a different core or a different insulation system.

3. Technical specifications

Which parameters appear here depends on the product family selected above.

Technical fields are optional — submit what you know.

4. Files and notes

Technical fields are optional — submit what you know.

PDF, PNG, JPG, JPEG, DWG, DXF, STEP, STP. Up to 4.0 MB per file, 4.5 MB in total.

One good drawing usually answers more of section 3 than the fields do. Send the PDF and leave the rest to us.
