MCR03
Resistors
Thick film rectangular resistors
MCR03 (1608 size)
!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 for FX, D resistors
Absorbs impact, facilitates mounting.
5) ROHM resistors have approved ISO–9001 certification.
Design and specifications are subject to change without notice. Carefully check the specification sheet supplied with the
product 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.
