Material 52 (Permeabilität 75

-52 Material: Dieses Material hat geringere Kernverluste bei hoher Frequenz und die gleiche Durchlässigkeit wie das -26 und -36  Material. Es ist beliebt für Hochfrequenz-Choke-Designs und in einer Vielzahl von Geometrien verfügbar.

‐52 Material: This material has lower core losses at high frequency and the same permeability as the ‐26 and -36 Material. It is popular for high frequency choke designs and available in a wide variety of geometries.
