GQ8B022940GBT Description

The GQ8B022940GBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors with a 294Ω resistance value, offering a tight 2% tolerance and a low ±50ppm/°C temperature coefficient. Encased in a ceramic substrate, it ensures excellent thermal stability and reliability across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating (0.05W per resistor) and a 100V maximum voltage rating, this network is ideal for precision analog and digital circuits requiring stable performance under varying conditions.
