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 A value is specified. For the application in magnetic amplifiers A is not a critical parameter. L L WARNING Do not use 3R1 cores close to their mechanical resonant frequency. For more information refer to 3R1 material specification in this data handbook. 2008 Sep 01 1620
