Stackpole's RPC1206 and RPC0805 offer superior pulse handling compared to standard chip resistors. 5% tolerance RPC's have best in class pulse handling. This performance is achieved through elimination of the resistance calibration trim, which is the weakest point in any chip resistor with respect to pulse handling. Standard chip resistors have pulse handling performance that varies greatly due to wide variations in laser trimming required to calibrate each part into value; this makes accurate characterization of the pulse handling behavior difficult. In addition, the RPC1206 in resistance values above 100 K ohms can withstand 1.5 KV surges of less than 50 microseconds; the RPC0805 100 KΩ value and higher can handle surges of over 1 KV.

Applications include power supply input/output protection, medical monitoring applications, many types of control systems such as those for motors and equipment, aviation and aerospace, protection for instrumentation, LED driver protection, communications infrastructure, commercial HVAC controls, wind and solar power controls, optical imaging, robotics, and automation.
