GUS-QS8A-01-2210-GB Description

The GUS-QS8A-01-2210-GB is a high-performance 8-resistor thin film network from TT Electronics/IRC, designed for precision applications in surface-mount PCB assemblies. This 221 Ohm, 2% tolerance resistor array features a QSOP-16 gull-wing package, ensuring reliable solderability and compact footprint (4.9mm × 6.02mm × 1.47mm). With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates across a wide temperature range of 70°C to 125°C (derated) and up to 125°C maximum, supported by a ±100ppm/°C temperature coefficient for stable performance under thermal stress. Its 100V maximum voltage rating and isolated (ISOL) circuit design make it suitable for signal conditioning, voltage division, and impedance matching in demanding environments.
