VPG RWC Series

The RWC precision wraparound SMD resistor series from Alpha Electronics offers resistances from 5Ω up to 30kΩ, all with a small 1206 chip size. By utilising Alpha’s Bulk Metal® foil resistor technology, they are able to offer low tolerances down to ±0.01% (between 1kΩ and 30kΩ) as well as a low TCR of ±2 ppm/°C (between -25°C and +125°C) from 100Ω up to 30kΩ. The Alpha RWC series also offers excellent load-life stability of ±0.005% typical (+70°C, 2000 hours at rated power).
