Anti-surge Chip Resistors

ESR10 (0805 size : 1 / 4W

)

Features

1) Power rating of 1 / 4W (MCR10 1/8W)

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 ISO9001- / ISO/TS 16949- certification.

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.
