GUS-QS8A-00-21R0-GF Description

The GUS-QS8A-00-21R0-GF from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a 16-pin QSOP package with gull-wing SMD termination, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) ideal for space-constrained PCB designs. Each resistor in the network features a 21Ω resistance with a tight 2% tolerance and a low ±250ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. The isolated (ISOL) circuit design allows independent resistor operation, while the 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding environments.

GUS-QS8A-00-21R0-GF Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and long-term stability compared to thick-film alternatives.
• High Power Density: 0.75W total power in a miniature QSOP package, optimizing thermal management.
