Resistors

Thick film rectangular Low Resistance Series

MCR25 (3225 size (1210 size) : 1 / 2W)

zFeatures

1) Highly reliable chip resistor

Ruthenium oxide resistive material offers superior resistance to the elements.

2) Electrodes not corroded by soldering

Suitable for re-flow soldering.

3) 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.

•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.
