GQ8A021872BBT Description

The GQ8A021872BBT 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 an 18.7KΩ resistance per element with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. Housed in a ceramic QSOP-16 package, it offers 0.75W (3/4W) total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic substrate enhances thermal and mechanical stability.
