Product Overview

SMD EPX7 Bobbin 4+4 Pins Type C

It belongs to the epx bobbins range, which holds 4 published part numbers. A bobbin is the part that fixes everything else in a wound component: the number of turns you can fit, the creepage between primary and secondary, the pin pattern the PCB has to accept and the temperature the winding survives during soldering.

Materials

Moulded body: LCP. Read the material guide for how thermoset and thermoplastic bodies behave in soldering.

Why Engineers Specify This Part

Every point below is taken from the published data for this part number rather than from a general claim.

Body material is fixed and stated

Moulded in LCP. The plastic is on the part page so nobody has to guess what survives your reflow or wave profile.

Footprint can be drawn before samples arrive

Pin distance 2.5mm and row distance on request are published, so the PCB land pattern is not blocked waiting for a sample.

Part of a 4 item EPX Bobbins range

Changing size later stays inside the same catalogue and the same tooling shop rather than becoming a new supplier search.

RoHS compliant

All products from CB Magnetics are RoHS compliant, which keeps the part usable in EU bound assemblies.

How It Is Made

Tool design, moulding, terminal insertion, assembly, electrical and dimensional test, then packing. The same route applies whether the part is a stock item or a new tool.

  1. Drawing review and tool design
  2. Steel cutting on the wire EDM and CNC machines in the tool room
  3. Injection moulding
  4. Terminal insertion and assembly
  5. Dimensional check in the measuring room
  6. Packing and shipping

Use Guide

Three checks before you commit a board layout or a winding programme to this part.

  1. Footprint. Match the published pin distance and row distance to your land pattern, then confirm both on the dimensioned drawing.
  2. Thermal. Check the stated plastic against your soldering profile. Thermoset bodies tolerate solder pot temperatures that melt many thermoplastics.
  3. Winding window. Confirm the section arrangement and the number of turns your wire gauge needs before ordering the tool or the first batch.
CAD files are released on request rather than as a public download. Ask for CAD on WhatsApp.

Questions Buyers Ask About This Part

What is SMD EPX7 Bobbin 4+4 Pins Type C moulded in

LCP. If your process needs a different plastic the same geometry can be quoted in another material.

What is the pin pitch and row spacing

Pin distance 2.5mm and row distance on request.

Can I get a drawing or a 3D model

Yes. Dimensioned drawings are sent as PDF and CAD files are released on request rather than as an open download. Ask for CAD on WhatsApp.

Are the parts RoHS compliant

Yes. All products from CB Magnetics are RoHS compliant.

Can this part be modified

Custom tooling design and injection moulding is one of our standing services, so pin count section splits and mounting features can be changed on a new tool. See how the tooling service works.

How do I get a price and lead time

Send the part number and the annual quantity. Price and lead time are quoted per part and per quantity rather than published, because both move with the material and the pin count. Send the quantity on WhatsApp.

Send The Part Number And Quantity

Quotes go out against a part number and an annual volume. If you have a drawing instead of a part number send that and it will be checked against existing tooling first.
