FERROXCUBE DATA SHEET TN14/9/5 Ferrite toroids Supersedes data of September 2004 2008 Sep 01 Ferroxcube Ferrite toroids RING CORES (TOROIDS) Effective core parameters SYMBOL Σ(I/A) Ve Ie Ae m Coating 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: 1500 V. Contacts are applied on the edge of the ring core, which is also the critical point for the winding operation.

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 AL value is specified. For the application in magnetic amplifiers AL is not a critical parameter. WARNING Do not use 3R1 cores close to their mechanical resonant frequency. For more information refer to “3R1” material specification in this data handbook.
