Ferrite toroids TN16/9.6/6.3
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: 1500 V.
Contacts are applied on the edge of the ring core, which is
also the critical point for the winding operation.
