ESR01 Datasheet, PDF (1/4 Pages) Rohm – Anti-surge thick film chip resistor

Anti-surge thick film chip resistor
ESR01 (1005 size : 1 / 5W)
Features
1) Industry’s smallest 1/5W resistors (MCR Series : 1005 size) made it possible to use resistors one size smaller.
2) Superior ESD resistance : 2kV (HBM, EIAJ4710)
3) ROHM resistors have approved ISO–9001, ISO/TS 16949 certification.
Applications
 Circuits requiring high rated power
 Xenon Flash Circuit
 Surge voltage countermeasure (i.e. from power supplies)
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.

Before 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.
