TX4.7/2.4/2.5

RING CORES (TOROIDS)

Effective core parameters

Coating

The cores are coated with epoxy. The colour is cream

(Sendust), grey (MPP) or khaki (High-Flux).

Maximum operating temperature is 200

°C.

Parylene coating is also available (transparent,

maximum operating temperature 130

°C).

Isolation voltage

AC isolation voltage : 1000 V (Parylene : 750 V).

Contacts are applied on the edge of the ring core, which is

also the critical point for the winding operation.
