FS Series Cores with High Magnetic Permeability

The FS series contains cores with high magnetic permeability. These cores have a particularly high initial permeability in the kHz bands, making them well suited for pulse transformers, noise filters and sensors. Their high magnetic permeability also enables more compact pulse power cores to be produced.

Features

High magnetic permeability enables more compact inductors with higher performance
High initial magnetic permeability in the kHz bands
Low loss, improving transformer performance
Minimal change in permeability in response to changes in magnetic field (strong iso-permeability)
