Sulfurous environments have a negative impact on film resistors by reacting with elements, particularly silver. Sulfide growth can cause resistors to go open circuit. Sulfur-resistant resistors had an approximately 20 times greater operating lifetime than the standard device. With the use of Bourns® sulfur-resistant film resistors and arrays, this corrosion related type of hard failure can be substantially reduced or eliminated, resulting in improved system reliability, performance, robustness and reduction of downtime.
