GUS-QS8A-02-4301-FA Description

The GUS-QS8A-02-4301-FA is a high-performance 8-resistor thin-film network from TT Electronics/IRC, designed for precision applications requiring stable resistance and tight tolerances. This 4.3KΩ, 1% tolerance device features a ±50ppm/°C temperature coefficient, ensuring minimal resistance drift across its 70°C to 125°C operating range. Housed in a 16-pin QSOP (QSOP-16) package, it offers a compact 4.9mm × 6.02mm footprint with gull-wing SMD termination, ideal for space-constrained PCB designs. Rated for 0.75W (3/4W) total power (0.1W per resistor) and 100V maximum voltage, it combines reliability with high power density. The isolated (ISOL) circuit design provides flexibility in circuit configurations, while thin-film technology delivers superior accuracy and stability over thick-film alternatives.

GUS-QS8A-02-4301-FA Features

• Precision Thin Film: Ensures low noise, high stability, and tight tolerance (1%) for critical analog/digital circuits.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) at 125°C max operating temperature, derated for extended reliability.
• Compact QSOP Package: 4.9mm × 6.02mm × 1.47mm dimensions with 0.64mm pitch, optimizing board space in dense layouts.
