Product Overview
25.4×15.24mm base 2+2 Pins The base is available with the four terminals or without terminals.
It belongs to the through hole base and case range, which holds 61 published part numbers. A wound toroid on its own cannot be placed by a machine or soldered by a wave.
Materials
Moulded body: GFN/PBT/PET. Terminals: CP Wire/Copper Wire. Flammability and thermal rating: UL 94-V0, Class F. 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 GFN/PBT/PET rated UL 94-V0, Class F. 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 20.32mm and row distance 10.16mm are published, so the PCB land pattern is not blocked waiting for a sample.
Terminal alloy and plating are specified
Terminals are CP Wire/Copper Wire, which is what determines solderability after storage.
Intended use is stated
For Vertical Mounting of wound Toroids of 30.48mm in diameter.
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.
- Drawing review and tool design
- Steel cutting on the wire EDM and CNC machines in the tool room
- Injection moulding
- Terminal insertion and assembly
- Dimensional check in the measuring room
- Packing and shipping
Use Guide
Three checks before you commit a board layout or a winding programme to this part.
- Footprint. Match the published pin distance and row distance to your land pattern, then confirm both on the dimensioned drawing.
- Thermal. Check the stated plastic against your soldering profile. Thermoset bodies tolerate solder pot temperatures that melt many thermoplastics.
- Winding window. Confirm the section arrangement and the number of turns your wire gauge needs before ordering the tool or the first batch.

Questions Buyers Ask About This Part
What is 25.4×15.24mm base for Totoidal core moulded in
GFN/PBT/PET, rated UL 94-V0, Class F. 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 20.32mm and row distance 10.16mm.
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.
