Compact Thick Film Chip Resistors

MCR03 (0603 size : 1 / 10W)



Features

1) Power rating of 1 / 10W

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) Resin protective coating absorbs impact, facilitates mounting.

5) ROHM resistors have approved ISO9001- / ISO/TS 16949- certification.

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.

E: Rated voltage (V) P: Rated power (W)

R: Nominal resistance (
