Anti-sulfur chip resistor arrays have very low resistance shifts

November 16, 2012 // By Julien Happich
The RAVS series of chip resistor arrays from Stackpole offers stable reliable performance in a wide variety of environments including those with high amounts of sulfur.

Stackpole's proprietary process and materials with reduced silver yield a chip resistor array with excellent long-term reliability under conditions where standard chip resistors fail. The RAVS series shows typical resistance shifts less than 0.1% after 240 hours at 40C, 95% R.H., 5 volt bias, and H2S concentration of 3ppm or greater. Applications for anti-sulfur chip arrays include automotive electronics, industrial and commercial equipment controls, marine electronics and anywhere gaskets, hoses, grommets, or oils and lubricants may be found.
The RAVS is available in 8-pin, 4 resistor circuits in 1, 1.6, and 3.1mm widths. Resistance values range from 10 ohms up to 1M in 200 ppm TCR and tolerances as low as 1%.
