PFC-D1206-03-39R0-9101-FD Description

The PFC-D1206-03-39R0-9101-FD from TT Electronics/IRC is a high-precision thin-film resistor network designed for surface-mount applications. This 3-pin 1206 package features two resistors with values of 39Ω and 9.1kΩ, offering a 1% tolerance and a ±25ppm/°C temperature coefficient for stable performance across a wide operating range. With a 0.25W (1/4W) total power rating and individual resistor ratings of 0.125W (1/8W), it is engineered for reliability in demanding circuits. The concave termination style ensures secure mounting, while its compact dimensions (3.2mm × 1.6mm × 0.61mm) make it ideal for space-constrained designs. Rated for 100V maximum voltage and 150°C maximum operating temperature, this network is suited for precision analog and digital applications.
