PFC-D1206-03-1200-3902-DD Description

The PFC-D1206-03-1200-3902-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 120Ω and 39kΩ, offering a tight tolerance of ±0.5% and a low temperature coefficient of ±25ppm/°C. With a 0.25W (1/4W) total power rating (0.125W per resistor), it operates reliably across a wide temperature range of -55°C to +150°C, derated up to 150°C. Its 100V maximum voltage rating and EAR99/Non-RoHS compliance make it suitable for industrial and non-automotive environments. Packaged in tape and reel (T/R), it ensures efficient assembly in high-volume production.

PFC-D1206-03-1200-3902-DD Features

• Precision Performance: Thin-film technology ensures low noise, high stability, and exact resistance matching (0.5% tolerance).
• Robust Construction: 1206 concave termination enhances solder joint reliability, while the rectangular SMD package (3.2mm x 1.6mm x 0.61mm) saves board space.
• Thermal Resilience: Operates at derated power up to 150°C, ideal for high-temperature environments.
• Dual-Resistor Design: Combines 120Ω and 39kΩ in a single network, reducing component count and improving signal integrity.
