GQ8A026190BT Description

The GQ8A026190BT 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 619Ω resistance value per element with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. Housed in a ceramic QSOP package with 16 gull-wing terminals, it offers 0.75W (3/4W) total power dissipation and 100V maximum voltage rating, making it suitable for high-reliability circuits. The isolated (ISOL) circuit design minimizes crosstalk, while the thin-film technology delivers superior accuracy and noise performance.
