GQ8A036802DBT Description

The GQ8A036802DBT 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 68K Ohm resistance value with an ultra-tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70 to 125°C). Encased in a ceramic QSOP package, it offers superior thermal stability and durability. The 16-pin gull-wing SMD configuration enables reliable surface-mount assembly, while the isolated (ISOL) circuit design provides electrical separation between resistors, making it ideal for precision analog and digital circuits.

GQ8A036802DBT Features
