The RCA series continues to see increased interest as robustness against harsh environmental conditions including potential sulfur became a point of concern in electronic designs. As Vishay offers not only the standard RCA series with other specification similar to that of a standard thick film chip resistor, but also versions that are Pulse proof, high power, or with long sides termination, options from the RCA series family of resistors are suitable for most any application using thick film surface mount chip resistors, especially in Automotive, Industrial, Alternative Energy, and other high reliability applications with potentially harsh environmental concerns.
