Rohm MCR18EZHFFL Low ohmic thick film chip resistor Datasheet

Low Ohmic Thick Film Chip Resistors
MCR18 (3216 size (1206 size) : 1 / 4W)
Features
1) Power rating of 1 / 4W
2) Highly reliable chip resistor Ruthenium oxide dielectric offers superior resistance to the elements.
3) Electrodes not corroded by soldering
Thick film makes the electrodes very strong.
4) ROHM resistors have approved ISO9001- / ISO/TS 19649- certification.
Ratings
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

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.
