GUS-QS8A-02-1651-BA Description

The GUS-QS8A-02-1651-BA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 8-resistor isolated network features a 1.65KΩ resistance value per resistor with an exceptional 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Housed in a 16-pin QSOP package with gull-wing SMD termination, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) ideal for space-constrained designs. Rated for 0.75W (3/4W) total power and 0.1W per resistor, it operates reliably from 70°C to 125°C with a 100V maximum voltage rating. The non-automotive, non-PPAP compliant device is supplied in a tube packaging for efficient assembly handling.

GUS-QS8A-02-1651-BA Features
