GS4B034991BBT Description

The GS4B034991BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding circuit applications. This 7-resistor array features a 4.99KΩ resistance value per element with an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range (70°C to 125°C). Housed in a ceramic SOIC-8 package, it offers 0.4W total power dissipation (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for precision analog and digital circuits. The gull-wing termination and surface-mount design facilitate automated PCB assembly, while its ±0.1mm dimensional tolerances ensure consistent placement accuracy.
