GUS-QS8A-03-4301-JB Description

The GUS-QS8A-03-4301-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter-Small Outline Package) device features 8 isolated 4.3KΩ resistors with a 5% 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 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 medium-voltage circuits.
