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: 1500 V.
Contacts are applied on the edge of the ring core, which is
also the critical point for the winding operation.
