Low Ohmic Thick Film Chip Resistors
MCR100 (6432 size (2512 size) : 1W)
zFeatures
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.

•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.
