UCR Series Low Ohmic Chip Resistors | New product new technology

Overview | Features | Applications | Lineup

Stable, low resistance operation that resists the effects of fluctuating ambient temperature.Superior rated voltage in the 2012 size: 1/3W

Overview

ROHM offers thick film resistors in the low resistance range between 11mΩ and 100mΩ that are robust against ambient temperature fluctuations. The unique structure improves thermal dissipation for superior rated power (1/3W) compared to similarly sized standard short terminal products.
