PFC-D1206LF02-49914991-FA Description

The PFC-D1206LF02-49914991-FA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 1206 package device features two 4.99KΩ resistors with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 150°C). With a 0.25W (1/4W) total power rating (0.125W per resistor) and a 100V maximum voltage rating, it is optimized for surface-mount (SMD) applications requiring reliable resistance matching and minimal drift. The concave termination style enhances solder joint reliability, while the tape-and-reel packaging facilitates automated assembly.
