GUS-QS8A-03-63R4-JF Description

The GUS-QS8A-03-63R4-JF from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications in surface-mount configurations. Encased in a 16-pin QSOP package with gull-wing terminations, this isolated network offers a 63.4Ω resistance per resistor with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it balances power handling with compact dimensions (4.9mm × 6.02mm × 1.47mm). The thin-film technology provides superior accuracy and reliability compared to thick-film alternatives, making it ideal for demanding environments.
