GQCA021132BBT Description

The GQCA021132BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP package features 12 isolated resistors, each with a 11.3K Ohm resistance and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division 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 maintains stable performance across a wide 70°C to 125°C derated power range. Its 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for precision analog and mixed-signal designs.
