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
Fig.1 TN14/9/5 ring core.
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.

1. Old permeability specification maintained.
2. 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 AL value is specified. For the application in magnetic amplifiers AL is not a critical parameter.
WARNING
Do not use 3R1 cores close to their mechanical resonant frequency. For more information refer to “3R1” material
specification in this data handbook.
