We offer a range of magnetics products for science, engineering, medical applications and more. Our product selection includes cores, wires, bobbins and accessories from major manufacturers.

About Our Bobbins

We stock coil formers from EPCOS (TDK), Fair-Rite, Ferroxcube, Magnetics and Miles-Platts.

As a major player in the magnetic materials industry, with an established product reach that extends into nearly all electrical and electronic devices on the market, TDK is a highly valued manufacturing partner. Dexter Magnetics carries the industry’s most extensive TDK product offering, with most products ready to ship immediately and delivered within 24 hours.

Fair-Rite bobbins are an effective and affordable solution for a range of applications where low but stable inductance values are required. Materials produced by Fair-Rite can be utilized in various innovative processes, and adhere to the IATF 16949 quality system to prevent product defects and variation.

Ferroxcube is one of the leading suppliers of soft magnetics ferrite components and accessories. As an approved distributor of Ferroxcube products, we're able to deliver Ferroxcube bobbins quickly and affordably. Ferroxcube products are popular in a wide range of applications, from computing electronics to automotive.

We are the leading source of Magnetics brand products. For more than two decades, we've supplied Magnetics' products, from ferrites and cores to bobbins. Dexter Magnetics is the longest running distributor of Magnetics' products, and we pride ourselves on being able to consistently provide reliable, high-quality Magnetics' products.

As a leading manufacturer of thermoplastic coil bobbins, Miles-Platts has established a well-deserved international reputation for reliability and service over the last 25 years. Dexter Magnetics remains the exclusive provider of Miles-Platts thermoplastic coil bobbins in North and South America.

Applications of Amorphous Cores

  • Transformers
  • Inductors
  • Chokes

Features of Amorphous Cores

  • Stable magnetic properties against temperature change
  • Permeability similar to high-end ferrites
  • Highly saturated flux density
  • Good at high-frequency range
  • Anti-bias current abilities
  • High permeability
  • Ultra-efficient
  • Low core loss

Ferrite Cores

We carry ferrite cores from leading manufacturers in the industry. Our ferrite cores are available in a wide array of geometries, grades and sizes.
Our selection includes Manganese-Zinc ferrites and Nickel-Zinc ferrites.

MnZn-based ferrites are characterized by low losses at high frequencies, and function especially well for power supplies and frequency converters that operate with fast-switching power semiconductors on a GaN basis.
NiZn-based ferrites are offer high material resistivity that's several orders of magnitude higher than a Manganese-Zinc ferrite.

Powder Cores

Our powder cores are exclusively provided by Magnetics. Primarily used in power inductor applications, these powder cores do not exhibit the thermal aging effects that are common with powdered iron cores. This is because Magnetics powder cores are not pressed with an organic binder. Magnetics powder cores feature some of the most performance materials in the industry, including Amoflux, High Flux, Kool Mu, MMP and MPP.
