GS4B028661JFT Description

The GS4B028661JFT from TT Electronics/IRC is a high-performance 7-resistor bussed network designed for precision applications in demanding electronic circuits. Housed in an 8-pin narrow SOIC (SOIC-C) ceramic package, this thin-film resistor network offers a 5% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance across all resistors. With a resistance value of 8.66KΩ and a ±50ppm/°C temperature coefficient, it provides excellent stability over a wide operating temperature range of -70°C to +125°C. The 0.05W (1/20) power rating per resistor and 100V maximum voltage rating make it suitable for low-power, high-reliability applications.
