RK73-RT
flat chip resistors (anti-sulfuration)
features
•
Excellent anti-sulfuration characteristic
due to using high sulfuration-proof inner
top electrode material
•
Excellent heat resistance and weather
resistance are ensured by the use of metal glaze thick film
•
High stability and high reliability with the triple-layer
structure of electrode
•
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 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 in the terminal part temperature”
in the beginning of the catalog.
While using under high power, the temperature of the product may increase depending on the condition of heat dissipation from PCB.
Be sure to check the terminal part temperature as well as precautions to use on delivery specification before use.

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