PFC-D1206-03-3302-3901-DD Description

The PFC-D1206-03-3302-3901-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 (33KΩ and 3.9KΩ) 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. Its concave termination style enhances solder joint reliability, while the 0.25W (1/4W) total power rating (0.125W per resistor) makes it suitable for compact, power-sensitive designs. The 100V maximum voltage rating and thin-film technology provide excellent long-term stability and low noise, ideal for precision analog and digital circuits.
