GUS-QS8A-02-1200-GC Description

The GUS-QS8A-02-1200-GC from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision applications in surface-mount PCB assemblies. This 120Ω thin-film resistor array features a 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP package with gull-wing terminations, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for demanding analog and digital circuits. Its isolated (ISOL) circuit design provides independent resistors, enhancing flexibility in circuit design.

GUS-QS8A-02-1200-GC Features
