GQ8A034642BT Description

The GQ8A034642BT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 46.4KΩ resistance per element with an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers 0.75W (3/4W) total power dissipation and 0.1W per resistor, making it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while its 100V maximum voltage rating and isolated (ISOL) circuit configuration enhance signal integrity in noise-sensitive environments.
