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.
Maximum operating temperature is 160
°C.
Isolation voltage
DC isolation voltage: 1000 V.
Contacts are applied on the edge of the ring core, which is
also the critical point for the winding operation.

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
L
value is specified. For the application in magnetic amplifiers A
L
is not a critical parameter.
WARNING
Do not use 3R1 cores close to their mechanical resonant frequency. For more information refer to
“3R1”
