EP Bobbins
EP bobbins for the shielded EP core shape used where radiated field has to be contained.
What This Series Covers
EP bobbins for the shielded EP core shape used where radiated field has to be contained. There are 20 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 EP Bobbins
How many ep bobbins are published
20 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
LCP; Pin Material: Phos Bronze, Phenolic, Phenolic; Pin Material: CP Wire, LCP; Pin Material: Phos Bronze, Phenolic; Pin Material: Phos Bronze, Phenolic; Pin Material: Phosphorus Bronze.
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.
