to impregnated dielectric.
TYPICAL APPLICATIONS
CONSTRUCTION
Single layer metallized paper. Encapsulated
and impregnated in self-extinguishing
material meeting the requirements of UL 94V-
0. The resistance in the metal layer is
utilized as series resistance, integrated
resistor.
RC unit for use in DC and AC applications
for:
– contact protection
– interference suppression of contacts
– transient suppression
