Anti-Sulfur Chip Resistor Arrays

The RAVS Series of anti-sulfur chip resistor arrays from Stackpole Electronics, Inc. has a reduced amount of silver in the inner terminations, which greatly reduces the susceptibility of the terminations to contamination from sulfur.  In "Flowers of Sulfur" testing per ASTM B 809-95, the RAVS Series shows resistance shifts of less than +/- 1%.  Standard chip resistor arrays would typically open completely or shift beyond 10% under these conditions.  This makes the RAVS a good solution for applications where many types of oils and lubricants, rubber gaskets, hoses, and grommets are used in close proximity to chip arrays. The RAVS is available in 8 pin 4 isolated resistor and 4 pin 2 isolated resistor configurations.  Sizes range from 0.04 by 0.04 in. to 0.2 by 0.12 in.   Resistance range is from 1 ohm to 10M ohm with tolerances as low as 1%.  Pricing varies with size, resistance value, and tolerance and ranges from $0.009 to $0.10 each in full reel quantities.
