GQ8A014642DBT Description

The GQ8A014642DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 16-pin QSOP (Quarter-Small Outline Package) device features 8 isolated resistors, each with a 46.4KΩ resistance, 0.5% tolerance, and a ±100ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. The ceramic case construction enhances thermal stability and durability, while the gull-wing termination facilitates reliable surface-mount (SMD) assembly. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is engineered for precision analog and digital circuits requiring tight tolerance and low drift.
