Resistors
Rev.A 1/6
Endured surge thick film chip resistor
ESR18 (1206 size: 1 / 3W)

Features
1) Power rating of 1 / 3W (MCR18 1 / 4W)
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 certification.
Design and specifications are subject to change without notice. Carefully check the specification sheet before using or
ordering it.

Limiting element voltage
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 (shortduration, highlevel 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.
