Low Ohmic Thick Film Chip Resistors
MCR01 (1005 size (0402 size) : 1 / 16W)
Features
1) Power rating of 1 / 16W
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/TS16949- certification.
Ratings

Operating temperature
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= P×R

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.
