PFC-D1206-03-3000-91R0-DD Description

The PFC-D1206-03-3000-91R0-DD from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 3-pin, 1206 concave SMD device integrates two resistors with values of 300Ω and 91Ω, 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 reliable performance in thermally challenging environments. The 100V maximum voltage rating and thin-film technology provide excellent stability and low noise, making it ideal for precision analog and digital circuits. Packaged in tape and reel (T/R), it suits automated assembly processes.
