GQCA028202BBT Description

The GQCA028202BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 24-pin QSOP (Quarter Small Outline Package) device integrates 12 isolated 82kΩ resistors with an exceptional ±0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C and a derated power range of 70°C to 125°C. The gull-wing termination facilitates reliable surface-mount (SMD) assembly, while the 100V maximum voltage rating and 1W total power dissipation (0.1W per resistor) make it suitable for precision analog and mixed-signal circuits.
