The RWA precision wraparound SMD resistor series from Alpha Electronics offers resistances from 100Ω up to 5kΩ, all with a small 0603 chip size. By utilising Alpha’s Bulk Metal® foil resistor technology, they are able to offer low tolerances down to ±0.05% (between 1kΩ and 5kΩ) as well as a low TCR of ±5 ppm/°C (between -25°C and +125°C) over the whole resistance range. The Alpha RWA series also offers excellent load-life stability of ±0.005% typical (+70°C, 2000 hours at rated power).
The RWA high precision wraparound surface-mount resistor series offers high precision and excellent stability thanks to Alpha’s Bulk Metal® foil resistor technology, making them suitable for the most demanding precision applications.
