Gapped ferrite toroids TN20/10/6.4 RING CORES (TOROIDS) Effective core parameters 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: 2000 V. Contacts are applied on the edge of the ring core, which is also the critical point for the winding operation.
