GQ8A0128R7JGT Description

The GQ8A0128R7JGT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications requiring stable resistance values and low thermal drift. Encased in a ceramic QSOP package, this 16-pin surface-mount component offers a 28.7Ω resistance per resistor with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.1W per resistor, it balances power dissipation and compactness, making it ideal for space-constrained designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while its 100V maximum voltage rating enhances durability in high-voltage circuits.
