GQ8A021202DBT Description

The GQ8A021202DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation applications. This 8-resistor array features a 12K Ohm resistance value with an ultra-tight 0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a ceramic QSOP package, it offers superior thermal and mechanical stability, with a 0.75W (3/4W) total power rating and 100V maximum voltage rating. The 16-pin gull-wing SMD termination ensures reliable surface-mount compatibility, while the isolated (ISOL) circuit design provides electrical separation between resistors.
