PFC-D1206-03-3902-1202-DD Description

The PFC-D1206-03-3902-1202-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 39KΩ and 12KΩ, offering a tight tolerance of ±0.5% and a low temperature coefficient of ±25ppm/°C for stable performance across a wide temperature range (70°C to 150°C derated, 150°C max). With a 0.25W (1/4W) total power rating (0.125W per resistor) and a 100V maximum voltage rating, it is engineered for reliability in precision circuits. The rectangular, tape-and-reel packaging ensures compatibility with automated assembly processes.
