GUS-QS8A-03-3832-GB Description

The GUS-QS8A-03-3832-GB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 38.3K Ohm resistance with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP package, it offers a compact footprint with 4.9mm length, 6.02mm depth, and 1.47mm height, making it ideal for space-constrained designs. Rated for 0.75W (3/4W) total power and 0.1W per resistor, it supports 100V maximum voltage, with gull-wing terminations for reliable surface-mount (SMD) assembly.
