GUS-QS8A-03-1541-FB Description

The GUS-QS8A-03-1541-FB is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount (SMD) applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 1.54KΩ resistance, 1% tolerance, and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.1W per resistor, it supports robust operation in compact designs. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while its 4.9mm × 6.02mm × 1.47mm dimensions make it ideal for space-constrained layouts.
