GUS-QS8A-02-4302-DB Description

The GUS-QS8A-02-4302-DB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated 43KΩ resistors with a tight tolerance of ±0.5% and a low temperature coefficient of ±50ppm/°C, ensuring stable performance across a wide operating range of -70°C to +125°C. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it offers superior power handling in a compact 4.9mm x 6.02mm x 1.47mm footprint. The gull-wing termination ensures reliable solder joints, while the 100V maximum voltage rating makes it suitable for high-voltage isolation circuits.
