PFC-D1206-03-9100-3301-DD Description

The PFC-D1206-03-9100-3301-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 device integrates two resistors with values of 910Ω and 3.3kΩ, offering a tight tolerance of ±0.5% and a low temperature coefficient of ±25ppm/°C for stable performance across a wide operating range. With a 0.25W (1/4W) total power rating (0.125W per resistor) and a maximum voltage rating of 100V, it is engineered for reliability in compact circuits. The thin-film technology ensures superior accuracy, low noise, and excellent long-term stability, making it ideal for precision analog and digital systems. Packaged in tape and reel (T/R) for automated assembly, it complies with industrial standards but is not RoHS-compliant.
