GUS-QS8A-02-2490-JA Description

The GUS-QS8A-02-2490-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low thermal drift. This 8-resistor isolated network features a 249Ω resistance per element with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). Housed in a compact 16-pin QSOP package, it offers a 0.75W (3/4W) total power rating and 0.1W per resistor, making it suitable for space-constrained, high-density PCB designs. The gull-wing termination ensures secure surface-mount (SMD) assembly, while the 100V maximum voltage rating enhances durability in demanding circuits.

GUS-QS8A-02-2490-JA Features

• Thin-Film Technology: Delivers superior stability, low noise, and tight tolerance (±50ppm/°C) for precision applications.
• High Power Handling: 0.75W total power rating (0.1W per resistor) outperforms standard networks in power dissipation.
