General-Purpose Anti-Sulfur Thick Film Resistors

Würth Elektronik General-Purpose Anti-Sulfur Thick Film Resistors are engineered for long-term performance and reliability at temperatures of up to +155°C. This WRIS-RSKS family of resistors is AEC-Q200 qualified and features an extra metal layer (nickel-chrome alloy) in the top-side electrode and is available in sizes ranging from 0402 to 1210. These resistors are protected against the formation of silver sulfide in environments rich in sulfur, a quality verified via ASTM B-809 testing. The series is offered in a broad range of resistance values, from 1Ω to 10MΩ, including 0Ω jumpers. These Würth Elektronik anti-sulfur thick film resistors are ideal for IT and communication, power supply and industrial controls, harsh environments, including construction machinery, as well as sulfurous and high air pollution areas, such as lighting and traffic controls.
