Compact Thick Film Chip Resistors
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.
ROHM resistors have approved ISO9001- / ISO/TS 16949- certification.

Item Conditions Specifications
Rated power
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)

Data Sheet MCR01
zBefore 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.
