Anti-sulfur chip resistor offers 2-watt power rating

Stackpole Electronics has added a 2-watt anti-sulfur chip resistor in a 2512 chip size to its RMCS family.

Stackpole Electronics has expanded its RMCS series with the RMCS2512 anti-sulfur chip resistor with a 2-watt (W) power rating in a 2512 chip size. The RMCS2512 … -HP option doubles the standard 2512 power rating and allows for the RMCS-HP to be used in higher power applications that may have previously used a different technology, said Stackpole.

Stackpole's RMCS2512 anti-sulfur chip resistorAnti-sulfur resistors are designed to withstand harsh environments with a high level of sulfur contamination, including environments with certain types of rubber gaskets or hoses, connectors, lubricants, and oils. What happens to general-purpose resistors in these environments is that the sulfur reacts with the silver inner terminations, causing them to increase in resistance values and eventually open, said Stackpole. Although anti-sulfur resistors have become more readily available, higher power versions are still difficult to find, added the company.

This 2512 anti-sulfur chip resistor can be used in applications such as industrial power and control applications, automotive controls and infotainment, machinery controls, servers and computers, data storage, marine controls, and welding equipment.

Stackpole offers other anti-sulfur resistor types such as the RTAN series of tantalum nitride precision chip resistors that are designed to operate in high-humidity environments. Applications include automotive electronics, industrial controls, portable medical devices, instrumentation, and aerospace.
