Magnetics Introduces High Permeability Ferrite M Material

Magnetics has introduced new high permeability ferrite M materials for signal, choke and filter applications such as common mode chokes, EMI suppression filters, signal processing and wideband transformers.

The M material is a new high permeability (15,000μ) material that provides good impedance performance over the switching frequency range. High permeability ferrite materials have excellent loss factors, frequency response, temperature performance and product consistency.
