Computing And Networking
LAN and RJ45 transformers, SMD bases and chokes for computing and network hardware.

What Goes Wrong In This Segment
The four problems that come up most often on enquiries from this market.
Every part has to be machine placeable
A wound toroid with loose leads cannot go down a pick and place line.
Board area is scarce
Height and footprint are fought over on every design review.
Common mode noise fails EMC late
Filtering added at the end of a project is the most expensive kind.
Long product life needs a stable supply
A part that disappears in two years is not usable in this market.
Typical Applications
- RJ45 and LAN transformer modules on network interfaces
- Common mode chokes on data and power lines
- SMD mounted toroids on dense boards
- Filter inductors on internal DC rails
How A Project Runs
- You send a drawing a reference design or a part list
- We check it against tooling we already own
- Material pin geometry and electrical values are confirmed in writing
- Samples from an existing tool, or a tool is cut for a new geometry
- Dimensional and electrical checks before shipment

Which parts do you supply into computing and networking
Surface mount bases and cases across a wide span of toroid diameters; Common mode chokes and filter inductors built on our own cases; RJ45 and LAN transformer modules.
Can you build the whole wound component
Yes. The former the core and the winding can come from one bill of materials and be quoted as a finished part.
What if the core shape I need is not listed
Send the drawing. Tool design and injection moulding are in-house services, so a new geometry is a tooling job.
Do you hold quality certification
ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018. All products are RoHS compliant.
How are prices set
Per part and per quantity. Send a part list or a drawing with annual volumes.
Send The Specification
A reference design a drawing or a part list is enough to start. Engineers reply, not a call centre.
