GUS-QS8A-03-4640-GG Description

The GUS-QS8A-03-4640-GG 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 464Ω resistance value per resistor with a tight 2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide operating temperature range of 70°C to 125°C. Housed 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 0.1W power rating per resistor (0.75W total) and a 100V maximum voltage rating, this non-automotive, non-PPAP compliant component is RoHS non-compliant and supplied in tube packaging.
