Compact Thick Film Chip Resistors
MCR10 (0805 size)
Features
1) Power rating of 1 / 8W (tolerance J,F)
2) Highly reliable chip resistor
Ruthenium oxide dielectric offers superior resistance to the elements.
3) Electrodes not corroded by soldering
Thick film makes the electrodes very strong.
4) Leading the world in development and mass production.
Since start of production in 1982 (first in the wold), this component has established a solid reputation as a general–purpose
chip resistor.
5) ROHM resistors have approved ISO9001- / ISO/TS 16949- certification.

Rated voltage
The voltage rating is calculated by the following equation.
If the value obtained exceeds the limiting element voltage,
the voltage rating is equal to the maximum operating voltage.
