ESR03_09 Datasheet, PDF (1/4 Pages) Rohm – Anti-surge thick film chip resistor

Anti-surge thick film chip resistor
ESR03 (0603 size : 1 / 5W)
zFeatures
1) Power rating of 1 / 5W (MCR03 1/10W)
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, ISO/TS 16949 certification.
Design and specifications are subject to change without notice. Carefully check the specification sheet before using or
ordering it.
zApplications
Automotive, LCD Monitor, projector, power supply, charger, inverter and so on.

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.

zBefore 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.
