GQCA034641DBT Description

The GQCA034641DBT 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 4.64KΩ resistance and an ultra-tight ±0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The device operates over a wide temperature range of 70°C to 125°C with a derated power capability, making it suitable for environments with thermal fluctuations. Its ceramic case style and gull-wing termination provide robust mechanical stability and reliable surface-mount compatibility. With a ±25ppm/°C temperature coefficient, this network minimizes resistance drift, critical for precision analog and digital systems.
