GS4B031581BBT Description

The GS4B031581BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. It features 7 resistors in a BUS configuration, each with a 1.58KΩ resistance and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy. Encased in a ceramic SOIC package, this component offers superior thermal stability and reliability, with a temperature coefficient of ±25ppm/°C and a maximum operating temperature of 125°C. The 8-pin gull-wing SMD design facilitates easy surface mounting, while the 0.4W total power rating (0.05W per resistor) makes it suitable for low-power circuits. Its 100V maximum voltage rating and thin-film technology provide excellent performance in precision analog and digital systems.
