Low Ohmic Thick Film Chip Resistors

MCR18 (3216 size (1206 size) : 1 / 4W)

Features

1) Power rating of 1 / 4W

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) ROHM resistors have approved ISO9001- / ISO/TS 19649- certification.

Ratings

Design and specifications are subject to change without notice. Carefully check the specification sheet before using or ordering

it.

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.

E: Rated voltage (V)

E= P×R

P: Rated power (W)

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.
