Base and Case for Toroidal Core and Coils from CB Magnetics

Who This Range Is For

A wound toroid on its own cannot be placed by a machine or soldered by a wave. A base, case or header turns it into a component with defined terminals, a defined height and a defined footprint. This range covers surface mount and through hole versions across a wide span of toroid diameters, in thermoset and thermoplastic bodies with tin plated terminals.

Typical buyers are power supply and magnetics designers fixing a footprint, and sourcing engineers at contract manufacturers who need one supplier to cover a whole series rather than a single size.

Problems It Solves

  • Geometry that is only revealed after samples arrive, which blocks the PCB layout.
  • A plastic body that will not survive the soldering profile in use.
  • Buying the former, the core and the winding from three suppliers and reconciling three tolerances.
  • A size change late in a project turning into a new supplier qualification.

Core Advantages

Surface mount and through hole in one range

Seventy SMD bases and cases and sixty one through hole bases, so the same toroid can be offered in both mounting styles.

Terminals specified not assumed

Terminal alloy and plating are stated per part, commonly phosphor bronze with 100 percent tin plating.

Sized to the toroid not to a catalogue slot

Base pages state the wound toroid diameter each part is intended to carry.

Self stripping wire friendly options

Thermoset bodies tolerate the solder pot temperatures used with self stripping magnet wire, which removes a stripping and tinning step.

Series In This Range

Pick the core series first then compare geometry inside it.

SMD Base and Case

SMD Base and Case

70 parts. Surface mount bases and cases that let a wound toroid be placed and reflowed like any other SMD part.

Through Hole Base and Case

Through Hole Base and Case

61 parts. Through hole bases headers and cases for wave soldered and hand assembled boards.

Parts In This Range

Questions About Toroid Mounts and Bases

How many parts are published in this range

134 part numbers are listed with their material pin geometry and rating. Parts outside the published list are made from customer drawings.

Do you sell from stock or make to order

Both. Catalogue geometries run from existing tools. New geometries are a tooling job, and tool design and injection moulding are handled in the same plant.

Can you supply the core as well as the plastic part

Yes. Silicon steel amorphous and nanocrystalline cores are part of the same catalogue, and complete wound transformers and inductors can be quoted as a finished component.

What certifications do you hold

ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018. All products are RoHS compliant.

How do I ask for a quotation

Send the part numbers and the annual quantity by WhatsApp or email. If you only have a drawing send that instead.
