GUS-QS8A-02-54R9-GG Description

The GUS-QS8A-02-54R9-GG from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 54.9 Ω resistance per element with a tight 2% tolerance and a low ±50 ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of -70°C to +125°C. Packaged in a 16-pin QSOP with gull-wing SMD termination, it offers a compact footprint (4.9 mm × 6.02 mm × 1.47 mm) ideal for space-constrained PCB designs. With a 0.75W total power rating (0.1W per resistor) and 100V maximum voltage rating, it balances power handling with precision. The non-automotive, non-PPAP compliant device is supplied in tubes, making it suitable for prototyping and small-scale production.
