MCR100_11 Datasheet, PDF (1/4 Pages) Rohm – Low Ohmic Thick Film Chip Resistors

Low Ohmic Thick Film Chip Resistors
MCR100 (6432 size (2512 size) : 1W)
Features
1) Highly reliable chip resistor
Ruthenium oxide dielectric offers superior resistance to the elements.
2) Electrodes not corroded by soldering
Suitable for re-flow soldering.
3) ROHM resistors have approved ISO9001- / ISO/TS 16949- certification.
Ratings
Design and specifications are subject to change without notice.
Carefully check the specification sheet supplied with the product before using or ordering it.

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)
Limiting element voltage 3.01V (9.1Ω)

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.
