Resistors

1/5

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.

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 (Ω)

E= P×R

Power must be derated according to the power derating curve in

Figure 1 when ambient temperature exceeds 70°C.

!Before using components in circuits where they will be exposed to transients such as pulse loads (short–duration, high– level loads), be certain to evaluate the

component in the mounted state. In addition, the reliability and performance of this component cannot be guaranteed if it is used with a steady state voltage that

is greater than its rated voltage.
