Ferrite toroids TX42/26/13 RING CORES (TOROIDS) Effective core parameters Coating The cores are coated with epoxy, flame retardant in accordance with “UL 94V-0”; UL file number E 228348. The colour is white. Maximum operating temperature is 200 °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.
