| MCR10 Resistors Thick film rectangular MCR10 (2012 size : 1 / 8W) !Features 1) Power rating of 1 / 8W 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 ISO-9001 certification. Design and specifications are subject to change without notice. Carefully check the specification sheet before using or ordering it. !Ratings Item Rated power Conditions Power must be derated according to the power derating curve in Figure 1 when ambient temperature exceeds 70C. 100 80 POWER LOAD (%) Specifications 0.125W (1 / 8W) at 70C 60 40 20 0 -55 0 70 100 155 AMBIENT TEMPERATURE (C) Fig.1 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.
