PFC-D1206-03-1100-3902-FD Description

The PFC-D1206-03-1100-3902-FD from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount circuits. This 3-pin, 1206 concave SMD device integrates two resistors with values of 110 Ω and 39 kΩ, offering a 1% tolerance and a low ±25 ppm/°C temperature coefficient. 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 demanding environments. The 100V maximum voltage rating and rectangular 1206 package (3.2mm x 1.6mm x 0.61mm) make it suitable for compact, high-density PCB designs.
