GQ8A021740JT

GQ8A021740JT Description

The GQ8A021740JT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 8-resistor network features a 174Ω resistance per element with a 5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring consistent performance across a wide 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 suitable for demanding environments. The isolated (ISOL) circuit design ensures minimal crosstalk between resistors, while the gull-wing termination enables secure surface-mount (SMD) assembly. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this component is ideal for compact, high-density PCB designs.
