GQ8A011273BT Description

The GQ8A011273BT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 127K Ohm resistance value with an ultra-tight 0.1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers superior thermal performance and mechanical durability. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability circuits. Its gull-wing termination and surface-mount design facilitate automated assembly.
