GQ8A039091FBT Description

The GQ8A039091FBT 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 9.09KΩ resistance per element with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers superior thermal stability and durability, making it ideal for high-reliability environments. The isolated (ISOL) circuit design ensures minimal crosstalk between resistors, while the gull-wing termination facilitates robust surface-mount (SMD) assembly. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, this network balances power handling with precision.
