GUS-QS8A-03-4990-GA Description

The GUS-QS8A-03-4990-GA from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a 16-pin QSOP (QSOP-16) package, this 499Ω, 2% tolerance resistor array offers excellent stability with a low ±25ppm/°C temperature coefficient. It features isolated (ISOL) circuit design, ensuring independent resistor functionality, and supports a maximum operating temperature of 125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it is optimized for surface-mount (SMD) applications requiring compact, reliable solutions.

GUS-QS8A-03-4990-GA Features
