The colour is white. CBW313 Maximum operating temperature is 160 C. Isolation voltage Dimensions in mm. DC isolation voltage: 1500 V. Fig.1 TN13/7.5/5 ring core. Contacts are applied on the edge of the ring core, which is also the critical point for the winding operation.

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 1630
