Summary: Long-term performance and reliability at temperatures up to +155°C.

resistors wrth Elektronik

wrth Elektronik general-purpose sulfur-resistant thick film resistors provide long-term performance and reliability at temperatures up to +155°C. This WRIS-RSKS series of resistors has an extra metal layer (nichrome) on the top electrode and comes in sizes ranging from 0402 to 1210. These resistors prevent the formation of silver sulfide in sulfur-rich environments, and their quality is verified by ASTM B-809 testing. This series offers a wide range of resistor values from 1 ohm to 10 milliohms, including 0 ohm jumpers. These wrth Elektronik sulfur-resistant thick film resistors are ideally suited for IT and communications, power and industrial controls, harsh environments including construction machinery, and areas containing sulfur and high air pollution such as lighting and traffic control.
