Low Ohmic Chip Resistors for Current Detection: UCR Series Not susceptible to changes in ambient temperature, resulting in stable resistances in the lower range (11m to 100m). The industry's highest rated current 1/4W in the 1608 size 1/3W in the 2012 size

Overview

ROHM offers a lineup of low-ohmic thick-film resistors: 11m to 100m. The rear-mount structure reduces resistance variations during mounting.
In addition, the proprietary design significantly improves heat dissipation characteristics, resulting in superior power ratings (i.e. 1/4W in the 1608 size, 1/3W in the 2012 size) compared with conventional short-terminal products.
