Find the component for your circuit

Transformers change or isolate voltage. Reactors and inductors limit, smooth or filter current. Choose the family that matches your circuit, then narrow by application.

  1. 1Pick the family that matches the job in your circuit.
  2. 2Filter by application to see representative units.
  3. 3Send the drawing or ratings for the unit you need. Each is built to order.

    Change or isolate voltage

    Transformers

    Transformers change voltage levels and isolate one circuit from another. We design and manufacture them to the voltage, power, frequency and mounting details in your drawing.

    Limit, smooth or filter current

    Reactors & Inductors

    Reactors and inductors store energy in a magnetic field to limit, smooth or filter current. We wind them to the inductance, current and terminal layout your application needs.

Manufacturing

Dedicated workshops for flat winding, edge winding and automation

Our lines are organised around custom work, so a one-off drawing and a repeat order both have a place on the floor.

How we work together

From your drawing to a confirmed quotation

A short, clear path for custom components. Each step is agreed with you before the next begins.

  1. Step 01

    Share your requirements

    Send a drawing, or describe the ratings, application and quantity if known.

  2. Step 02

    Technical review

    We study the drawing and specification and ask about anything that needs clarifying.

  3. Step 03

    Quotation

    You receive a quotation for the specification that has been confirmed.

  4. Step 04

    Winding and assembly

    Coils are wound and assembled to the agreed requirements in our workshops.

  5. Step 05

    Testing and shipment

    Test steps and shipping arrangements are agreed with you for each project.
