thick film resistors for high voltage
EU
features
•
High resistance resistors for high voltage circuits
•
Thin SIP shape
•
The flame retardant coats corresponding to UL94V-0
are used
•
Thick film resistors (RuO
2
) ensure high stabilities
in life and change in aging
•
Products with lead-free terminations meet EU RoHS
requirements. EU RoHS regulation is not intended for
Pb-glass contained in electrode, resistor element and glass.
