Current-Sense Resistors Handle Up To 3W At +80°C

Described as economical, surface-mount metal-element current-sense resistors that promise to maximize thermal performance and minimize power consumption, the RoHS-compliant ULR series feature tight TCRs and low inductance values. They are available with current ratings from 1W to 3W at +80°C and in resistance values from 0.5 to 10 milliOhms with standard tolerances of ±1% and ±5% and TCRs as low as ±50 ppm/°C. Operating temperature ranges from -55°C to +170°C. Resistors outside these specs are possible upon request. Pricing for the ULR series is approximately $0.14 each/100,000.
