MCR50_09 Datasheet, PDF (1/4 Pages) Rohm – Thick Film Chip Resistors

Thick Film Chip Resistors
MCR50 (2010 size : 1 / 2W)
zFeatures
1) Made of same material as the general purpose chip resistors (MCR10 / 18).
2) Highly reliable chip resistor
Ruthenium oxide dielectric offers superior resistance to the elements.
3) Electrodes not corroded by soldering
Suitable for re-flow soldering.
4) ROHM resistors have approved ISO9001- / ISO/TS 16949- certification. Design and specifications are subject to change
without notice.
Carefully check the specification sheet supplied with the product 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
E: Rated voltage (V)
P: Rated power (W)
R: Nominal resistance (Ω)

•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.
