EPC Bobbins
EPC bobbins for the EPC core family used in compact switching transformers.
What This Series Covers
EPC bobbins for the EPC core family used in compact switching transformers. There are 17 published part numbers, and every one lists the plastic, the pin count and the pin geometry where the drawing states them.
If a geometry in this series is close but not exact, the tool room can modify pin counts, section splits and mounting features on a new tool rather than forcing a redesign around a stock part.

Questions About EPC Bobbins
How many epc bobbins are published
17 part numbers, listed above with material and pin geometry.
What if my size is not in the list
Send the drawing. Tool design and injection moulding are in-house services, so a size that is not in the catalogue is quoted as a tooling job rather than turned away.
Which plastics are used in this series
Phenolic; Pin Material: CP Wire, Phenolic PM9630; Pin Material: CP Wire, LCP E4008; Pin Material: CP Wire.
Can you supply the matching core
Yes. Silicon steel amorphous and nanocrystalline cores are in the same catalogue and complete wound components can be quoted.
Do you provide drawings and CAD
Dimensioned drawings are sent as PDF on request. CAD files are released on request via WhatsApp or email rather than as an open download.
Send Your Part List
Catalogue parts are quoted from existing tooling. Anything outside the list is quoted from your drawing.
