GUS-QS8A-02-2050-JA Description

The GUS-QS8A-02-2050-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 8-resistor isolated network features a 205Ω resistance value per resistor with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Encased in a 16-pin QSOP package with gull-wing terminations, it offers a compact footprint (4.9mm length × 6.02mm depth × 1.47mm height) and a 0.64mm terminal pitch, making it ideal for space-constrained designs. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this non-automotive, non-PPAP component is RoHS non-compliant and supplied in tube packaging.
