PFC-D1206-03-1203-1802-DD Description

The PFC-D1206-03-1203-1802-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 component integrates two resistors (120KΩ and 18KΩ) with a tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°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 compact circuits. The non-automotive, non-PPAP compliant device is supplied in tape and reel (T/R) packaging for efficient assembly.
