GQCA034531DBT Description

The GQCA034531DBT 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 4.53KΩ 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 low ±25ppm/°C temperature coefficient, making it ideal for environments with thermal fluctuations. Its ceramic case style and gull-wing termination provide robust mechanical stability and reliable surface-mount compatibility. Packaged in a tube, this non-automotive component is suited for industrial and commercial applications where precision and durability are critical.
