GS4B035110FFT

GS4B035110FFT Description

The GS4B035110FFT from TT Electronics/IRC is a high-performance 7-resistor bussed network designed for precision applications. Housed in an 8-pin narrow SOIC (SOIC-C) ceramic package, it features a 511Ω resistance value with a tight ±1% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance. Its thin-film technology delivers excellent stability with a low ±25ppm/°C temperature coefficient, making it suitable for environments with fluctuating temperatures. Rated for 0.05W (1/20W) per resistor and 0.4W total power dissipation, it operates reliably within a 70°C to 125°C derated power range, with a maximum operating temperature of 125°C. The 100V maximum voltage rating and surface-mount gull-wing termination enhance its versatility in compact PCB designs.
