Film resistors suited to high sulfur and high humidity applications

Environmental stability for thin film resistors has grown more important with increased electronic content. For example, sulfur contamination for film resistors is becoming a more central issue for a broad range of end products. Electronic devices and circuitry can encounter sulfur in the presence of gaskets, hoses, oils, lubricants, and atmospheric gasses in highly industrial areas. Finding anti-sulfur resistors may be difficult and seeking those that are also moisture-resistant is yet more challenging.

The RNCS-AS series from Stackpole Electronics provides a precision thin film anti-sulfur option with outstanding anti-sulfur performance as measured by ASTMB-809-95 sulfur testing with a maximum shift of lower than 0.5%. The series is also highly resistant to moisture corrosion, with lower than 0.1% resistance shift under industry standard testing at 85C, 85% relative humidity, and 10% rated power.

The device is ideal for various industrial, medical, test and measurement, and precision control applications.
