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.

Limiting element voltage 50V
Power must be derated according to the power derating curve in
Figure 1 when ambient temperature exceeds 70°C.
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.

!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.
