GUS-QS8A-02-2490-BA Description

The GUS-QS8A-02-2490-BA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor isolated network features a 249Ω resistance value per resistor 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 compact 16-pin QSOP (QSOP-16) package, it offers a 0.75W (3/4W) total power rating and 0.1W per resistor, making it suitable for high-density PCB designs. The gull-wing termination and 0.64mm terminal pitch facilitate reliable surface-mount (SMD) assembly, while its isolated circuit design (ISOL) provides flexibility in circuit configurations.
