Low Ohmic Thick Film Chip Resistors
MCR18 (3216 size (1206 size) : 1 / 4W)
zFeatures
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.

Rated voltage
The voltage rating is calculated by the following equation.
E= P×R
E: Rated voltage (V)
P: Rated power (W)
R: Nominal resistance (Ω)
