PFC-D1206-03-3301-4301-DD Description

The PFC-D1206-03-3301-4301-DD from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 1206 package device features two resistors (3.3KΩ and 4.3KΩ) with an ultra-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. The 0.25W (1/4W) total power rating (0.125W per resistor) and 100V maximum voltage rating make it suitable for compact, high-reliability circuits. Its concave termination style enhances solder joint integrity, while the tape-and-reel packaging supports automated assembly processes.
