Resistors
Thick film rectangular
MCR01 (1005 size : 1 / 16W)
zFeatures
1) Extremely small light
Area ratio is 60% smaller than that of chip 1608, while weight ratio has been cut 75%.
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) Flat surface further facilitates mounting
Mounting can also be automated.
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.

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.

zBefore using components in circuits where they will be exposed to transient s such as pulse loads (short–duration, high– level loads), be cert ain 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 volt age.
