GQ8A021273BT Description

The GQ8A021273BT 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 ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP ceramic package, it offers excellent thermal stability and durability, making it suitable for harsh environments. The isolated (ISOL) circuit design ensures minimal crosstalk between resistors, while the gull-wing termination facilitates reliable surface-mount (SMD) assembly. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, this network is engineered for precision analog and digital circuits.
