GQCA029761DBT Description

The GQCA029761DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation circuit applications. This 24-pin QSOP (Quarter-Small Outline Package) device features 12 isolated resistors, each with a 9.76KΩ resistance value and a tight ±0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division. The ceramic case style and gull-wing termination enable robust surface-mount (SMD) integration, while the ±50ppm/°C temperature coefficient guarantees stable performance across a -70°C to +125°C operating range. With a 100V maximum voltage rating and 0.1W power dissipation per resistor, this network is ideal for precision analog and digital systems.
