What This Series Covers

EE bobbins in horizontal and vertical formats across a wide range of core sizes and pin counts. There are 42 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 EE Bobbins

How many ee bobbins are published

42 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, GFN, PET, PET FR530, LCP.

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.
