Coating

coating PA11

(≈0.3)

The cores are coated with polyamide 11 (PA11), flame

retardant in accordance with “UL 94V-2”.

Isolation voltage

CBW307

DC isolation voltage: 2000 V.

Contacts are applied on the edge of the ring core, which is

also the critical point for the winding operation.

Note

1. Due to the rectangular BH-loop of grade 3R1, inductance values strongly depend on the magnetic state of the ring

core and measuring conditions. Therefore no A_Lvalue is specified. For the application in magnetic amplifiers A_Lis

not a critical parameter.

WARNING

Do not use grade 3R1 cores close to their mechanical resonant frequency. For more information refer to “3R1”
