Resistors
ESR10
Endured surge thick film chip resistor
ESR10 (0805 size : 1 / 4W)
zFeatures
1) Power rating of 1 / 4W (Rated power is more than twice that of MCR series)
2) Superior anti surge to MCR series
3) Highly reliable chip resistor
Ruthenium oxide dielectric offers superior resistance to the elements.
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.

Rated voltage
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
Nominal resistance See Table 1.
