PFC-D1206-03-4701-6802-DD Description

The PFC-D1206-03-4701-6802-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 (4.7KΩ and 68KΩ) with a tight tolerance of ±0.5% and a low temperature coefficient of ±25ppm/°C, ensuring stable performance across a wide operating range (-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 ideal for precision voltage division and signal conditioning in compact PCB designs. Packaged in tape and reel (T/R) for automated assembly, it combines reliability with manufacturability.

PFC-D1206-03-4701-6802-DD Features

• Dual-Resistor Network: Integrates 4.7KΩ and 68KΩ resistors in a single 1206 footprint, saving board space.
• High Precision: ±0.5% tolerance and ±25ppm/°C TCR for stable performance in temperature-varying environments.
