PFC-D1206-03-1802-3901-DD Description

The PFC-D1206-03-1802-3901-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 component features two resistors with values of 18KΩ and 3.9KΩ, offering a tight tolerance of ±0.5% and a low temperature coefficient of ±25ppm/°C for stable performance across a wide operating range (-55°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 engineered for reliability in precision circuits. The thin-film technology ensures low noise and high accuracy, while the concave termination style enhances solder joint integrity. Packaged in tape and reel (T/R), it is optimized for automated assembly.
