GQ8A038872BT Description

The GQ8A038872BT 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 88.7KΩ resistance per element with an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a ceramic QSOP package, it offers superior thermal stability and durability, with a 0.75W (3/4W) total power rating and 0.1W per resistor. The 16-pin gull-wing SMD termination ensures reliable surface-mount compatibility, while the 100V maximum voltage rating makes it suitable for high-voltage isolation circuits.
