GS4B031781JAT Description

The GS4B031781JAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for surface-mount applications. It features 7 resistors with a 1.78KΩ resistance value, 5% tolerance, and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in an 8-pin SOIC ceramic package, it offers a 0.4W total power rating (0.05W per resistor) and a maximum voltage rating of 100V. Its gull-wing termination and 1.27mm terminal pitch facilitate reliable PCB mounting, while its compact dimensions (4.9mm x 5.99mm x 1.45mm) make it suitable for space-constrained designs.
