PFC-D1206-03-68R0-3301-DD Description

The PFC-D1206-03-68R0-3301-DD from TT Electronics/IRC is a high-precision thin-film resistor network designed for surface-mount applications. This 1206 package (3.2mm × 1.6mm × 0.61mm) features two resistors with values of 68Ω and 3.3kΩ, offering a tight tolerance of ±0.5% and a low temperature coefficient of ±25ppm/°C. Rated for 0.25W (1/4W) total power dissipation (0.125W per resistor), it operates reliably across a wide temperature range of -55°C to +150°C, with derated performance up to 150°C. Its concave termination style ensures robust solder joint integrity, while the 100V maximum voltage rating makes it suitable for moderate-voltage circuits.
