GUS-QS8A-03-3900-GB Description

The GUS-QS8A-03-3900-GB from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision applications in surface-mount PCB assemblies. This 390Ω, 2% tolerance thin-film resistor network offers a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Encased in a 16-pin QSOP (QSOP-16) package with gull-wing terminations, it features a compact footprint (4.9mm × 6.02mm × 1.47mm) and a 0.64mm terminal pitch, making it ideal for space-constrained designs. With a 0.1W power rating per resistor and a total power dissipation of 0.75W, it balances efficiency and reliability. The isolated (ISOL) circuit design allows independent resistor functionality, enhancing flexibility in circuit configurations.
