This document is the specification of EP13-3C90 basic core, including weight, air gap, marking, etc.
The EP13-3C90 is a magnetic core offered by Ferroxcube. The sheet provides basic core data such as weight, air‑gap options and a list of part numbers for various inductance values.
Magnetic characteristics are given according to IEC 205, including saturation flux density, frequency range and inductance measurements for both gapped and ungapped core configurations. Marking references and tolerances are also listed. This manual is written in Polish.
| Weight (single core) | 2.4 g |
|---|---|
| Weight (set) | ≈ 4.8 g per set |
| Saturation flux density (Bsat) | > 320 mT |
| Inductance (A) measured with ungapped core | value given in nH per part number |
A single EP13-3C90 core weighs 2.4 g.
The EP13-3C90 core has a saturation flux density greater than 320 mT.
Inductance (A) is measured in nanohenries with the core in an ungapped configuration.
