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

If any questions should arise whether to use the “Rated Ambient Temperature” or the “Rated Terminal Part Temperature,” please give priority to the
“Rated Terminal Part Temperature.” Prior to use and for more details refer to “Introduction of the derating curves on the terminal part temperature”
