PFC-D1206-03-1801-3301-DD Description

The PFC-D1206-03-1801-3301-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 with values of 1.8KΩ 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 (-55°C to +150°C). With a 0.25W (1/4W) total power rating (0.125W per resistor) and a 100V maximum voltage rating, it is engineered for reliability in precision circuits. The 3-pin concave termination ensures secure mounting, while the tape-and-reel packaging facilitates automated assembly.
