GUS-QS8A-03-1471-DB Description

The GUS-QS8A-03-1471-DB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates eight isolated 1.47KΩ resistors with a tight tolerance of ±0.5% and a low temperature coefficient of ±25ppm/°C, ensuring stable performance across a wide operating range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.1W per resistor, it offers robust power handling in a compact 4.9mm x 6.02mm x 1.47mm surface-mount package. The gull-wing termination ensures reliable solder joints, while the 100V maximum voltage rating makes it suitable for high-voltage circuits.
