Note
1. 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 grade 3R1 cores close to their mechanical resonant frequency. For more information refer to
