GQ8A023742BT Description

The GQ8A023742BT 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 37.4KΩ resistance value per element with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring exceptional stability across a wide operating temperature range of -55°C to +125°C. Housed in a ceramic QSOP-16 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 design enhance safety in sensitive environments.
