Coating
The cores are coated with parylene C, flame retardant in
accordance with “UL 94V-2”; UL file number E 194397.
The coating is transparent.
Maximum operating temperature is 90 °C.
Isolation voltage
DC isolation voltage: 1000 V.
Contacts are applied on the edge of the ring core, which is
also the critical point for the winding operation.
