RING CORES (TOROIDS)
Effective core parameters
Coating
The cores are coated with polyamide 11 (PA11), flame
retardant in accordance with “UL 94V-2” ; UL file number
E 45228 (M). The colour is white.
Isolation voltage
DC isolation voltage: 1500 V.
Contacts are applied on the edge of the ring core, which is
also the critical point for the winding operation.

Ferrite toroids
Old permeability specification maintained.
Due to the rectangular BH-loop of 3R1, inductance values strongly depend on the magnetic state of the ring core and measuring
conditions. Therefore no A
