Rev.K 1/4
Comp act Thick Film Chip Resistors
MCR03 (0603 size)
zFeatures
1) Power rating of 1 / 10W
2) Highly relia ble 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) Resin protective coating absorbs impact, facilitates mounting.
5) ROHM resistors have approved ISO9001- / ISO/TS 16949- certification.

Limiting element voltage 50V
Power must be derated according to the power derating curve in
Figure 1 when ambient temperature exceeds 70°C.
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.

zBefore using components in circuit s where they will be exposed to transients such as pulse loads (short–dura tion, high– level loads), be certain to ev aluate the
component in the mounted state. In additio n, the reliability and performance of this component cannot be guaranteed if it is used with a steady st ate voltage that
is greater than its rated voltage.
