EP7-3C90 is a ferrite core chip with both no gap and ungapped versions. The magnetic induction of the no gap version is 1200 ± 25%, and the magnetic induction of the ungapped version is 200 ± 5%, 160 ± 8%, 100 ± 5%, and 40 ± 3%.
This handbook provides technical data for the Ferroxcube EP7-3C90 magnetic core, including dimensions, weight, magnetic characteristics, and marking information.
The document lists core dimensions (A = 10.7 mm, V = 165 mm), weight (0.7 g per piece, 1.4 g per set), saturation flux density (Bsat = 250 mT), and marking codes such as “6” on the core back. This manual is written in Polish.
