endured pulse power flat chip resistors
(anti-surge, anti-sulfuration)
features
EU
•
Excellent anti-sulfuration characteristic
due to using high sulfuration-proof inner
top electrode material/pulse
•
Superior to RK73 series chip resistors
in pulse withstanding voltage and high power
•
Marking: White three-digit on wine red protective coat
•
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.

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” in the beginning of the catalog. Also, contact KOA prior to usage and for the max. working voltage and max. overload voltage.

For resistors operated at an ambient temperature
of 70°C or above, a power rating shall be derated
in accordance with the derating curve.
For resistors operated at a terminal part temperature of described for each size or above,
a power rating shall be derated in accordance with the derating curve.
Please refer to “Introduction of the derating curve based on the terminal part temperature”
in the beginning of our catalog before use.
