GUS-QS8A-03-1473-GA Description

The GUS-QS8A-03-1473-GA 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 eight isolated 147KΩ resistors with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -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 solderability, while the 100V maximum voltage rating makes it suitable for high-voltage circuits.
