Resistors
1/6
Endured surge thick film chip resistor
ESR10 (2012 size : 1 / 4W)
zFeatures
1) Power rating of 1 / 4W (Rated pow er is more than tw ice that of MCR series)
2) Superior anti surge to MCR series
3) Highly reliable chip resistor
Ruthenium oxide dielectric offers superior resist ance to the elements.
4) ROHM resistors have approved ISO–9001 certification.
Design an d specifications are sub ject to change without notice. Carefully check the s pecification sheet 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.
E: Rated voltage (V)
P: Rated power (W)
R: Nominal resistance (Ω)
E= P×R
Power must be derated according to the power derating curve in
Figure 1 when ambient temperature exceeds 70°C.

zBefore using components in circuit s where they will be ex posed 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 volt age.
