Alpha RWB Series

The RWB precision wraparound SMD resistor series from Alpha Electronics offers resistances from 10Ω up to 10kΩ, all with a small 0805 chip size. By utilising Alpha’s Bulk Metal® foil resistor technology, they are able to offer low tolerances down to ±0.02% (between 1kΩ and 10kΩ) as well as a low TCR of ±2 ppm/°C (between -25°C and +125°C) from 100Ω up to 10kΩ. The Alpha RWB series also offers excellent load-life stability of ±0.005% typical (+70°C, 2000 hours at rated power).
