GQ8B0129R4GT Description

The GQ8B0129R4GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors with a 29.4Ω resistance value, offering a tight 2% tolerance and a low ±100ppm/°C temperature coefficient. Encased in a ceramic package, it ensures excellent thermal stability and durability. The network operates over a wide temperature range (70°C to 125°C) and delivers a total power rating of 0.75W (3/4W), with 0.05W (1/20W) per resistor. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the 100V maximum voltage rating makes it suitable for robust circuit designs.
