GUS-QS8A-01-1581-JA Description

The GUS-QS8A-01-1581-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount configurations. This 16-pin QSOP package features 8 isolated resistors, each with a 1.58KΩ resistance, 5% tolerance, and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it balances power handling and compactness. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while its 4.9mm × 6.02mm × 1.47mm dimensions make it suitable for space-constrained designs.
