PFC-D1206-03-3901-5102-DD

PFC-D1206-03-3901-5102-DD Description

The PFC-D1206-03-3901-5102-DD from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 1206 package device integrates two resistors (3.9KΩ and 51KΩ) with a tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -55°C to +150°C. With a 0.25W (1/4W) total power rating and 100V maximum voltage rating, it is engineered for reliability in compact, high-density circuits. The concave termination style enhances solder joint integrity, while the tape-and-reel packaging facilitates automated assembly.
