PFC-D1206-03-3902-4701-DD Description

The PFC-D1206-03-3902-4701-DD from TT Electronics/IRC is a high-precision thin-film resistor network designed for surface-mount applications. This 1206 package device integrates two resistors (39KΩ and 4.7KΩ) with a tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range (70°C to 150°C). With a 0.25W (1/4W) total power rating and 100V maximum voltage rating, it is engineered for reliability in demanding circuits. The 3-pin concave termination enhances solderability, while the tape-and-reel packaging facilitates automated assembly.
