Established in 1951, Dexter Magnetic Technologies has proven to be the ultimate industry leader worldwide of magnetic assemblies and products in fabrication, design and specification.

Based on traditional laminated E cores, ferrite E cores are one of the well-known shapes in the industry. They are easy to assemble and wind by using mounting hardware and standard bobbins, and they are very affordable. Transformers of inverter, power and broadband, telecom and power inductors, and differential are typical applications for E cores. Some examples of E cores from this company include E55/28/21 CORE, E22/6/16 PLANAR CORE, E38/8/25 PLANAR CORE, E42/21/20 KOOL MU 026 PERM and E41/17/12 CORE.
