GQ0A021272BAT

GQ0A021272BAT Description

The GQ0A021272BAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP package integrates 10 isolated resistors, each with a 12.7KΩ resistance and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in signal conditioning, voltage division, and feedback circuits. The ceramic case provides robust thermal and mechanical stability, while the gull-wing termination enables reliable surface-mount (SMD) assembly. With a ±50ppm/°C temperature coefficient and a 125°C maximum operating temperature, this network delivers stable performance across a wide 70°C to 125°C derated power range. Its 100V maximum voltage rating and 1W total power dissipation (0.1W per resistor) make it suitable for precision analog and mixed-signal systems.
