PFC-D1206-03-51R0-3902-DD Description

The PFC-D1206-03-51R0-3902-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 (51Ω and 39kΩ) 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 maximum operating temperature of 150°C and a power rating of 0.25W (1/4W), it is engineered for reliability in precision circuits. The concave termination style enhances solder joint integrity, while the 100V maximum voltage rating makes it suitable for moderate-voltage applications.
