HV73-RT
flat chip resistors for high voltage
(anti-sulfuration)
EU
features
•
Superior to RK73 series in maximum
working voltage
•
Suitable for flow and reflow solderings
•
Products meet EU RoHS requirements. EU RoHS
regulation is not intended for Pb-glass contained in
electrode, resistor element and glass.
•
Excellent anti-sulfuration characteristics due to using
high sulfuration-proof inner top electrode material
