GQ8A033091CBT Description

The GQ8A033091CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor isolated network features a 3.09KΩ resistance value per resistor with an ultra-tight tolerance of ±0.25% and a low temperature coefficient of ±25ppm/°C, 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 excellent thermal stability and durability, making it ideal for precision analog and digital circuits. The gull-wing termination facilitates reliable surface-mount (SMD) assembly, while the 0.1W power rating per resistor (0.75W total) and 100V maximum voltage rating ensure robust operation in compact designs.
