PFC-D1206-03-1202-1301-DD Description

The PFC-D1206-03-1202-1301-DD from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 3-pin SMD (1206 case size) component integrates two resistors with values of 12KΩ and 1.3KΩ, offering a tight tolerance of ±0.5% and a low temperature coefficient of ±25ppm/°C. With a 0.25W (1/4W) total power rating (0.125W per resistor) and a maximum operating temperature of 150°C, it ensures stable performance in thermally challenging environments. The concave termination style enhances solder joint reliability, while the 100V maximum voltage rating makes it suitable for voltage divider circuits. Packaged in tape and reel (T/R), it is optimized for automated assembly processes.
