Resistors
Thick film rectangular
MCR25
(3225 size: 1 / 4W)
!
Features
1) Made of same material as the general purpose chip resistors (MCR10 / 18).
2) Highly reliable chip resistor
Ruthenium oxide resistive material offers superior resistance to the elements.
3) Electrodes not corroded by soldering
Both flow and reflow soldering can be used.
4) ROHM resistors have approved ISO-9001 certification.
Design and specifications are subject to change without notice. Carefully check the specification sheet before using or
ordering it.

Max. intermittent overload voltage
The voltage rating is calculated by the following equation. If the value
obtained exceeds the maximum operating voltage, the voltage rating is
equal to the maximum operating voltage.
Power must be derated according to the power derating curve in
Figure 1 when ambient temperature exceeds 70C.

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.
