GUS-QS8A-03-3922-JF Description

The GUS-QS8A-03-3922-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device features 8 isolated resistors, each with a 39.2KΩ resistance value and a tight ±5% tolerance. With a ±25ppm/°C temperature coefficient, it ensures stable performance across a wide operating range of -70°C to +125°C. The 0.75W (3/4W) total power rating and 100V maximum voltage rating make it suitable for demanding circuits requiring reliability under varying conditions. Packaged in a tube, this RoHS non-compliant component is ideal for industrial and commercial electronics where isolation and precision are critical.

GUS-QS8A-03-3922-JF Features

• Thin-Film Technology: Delivers high accuracy and low noise, ideal for signal conditioning and analog circuits.
• Compact QSOP Package: Measures 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with ±0.1mm length/height tolerances, enabling high-density PCB layouts.
• Isolated Resistors (ISOL): Each of the 8 resistors is electrically isolated, reducing crosstalk in multi-channel systems.
• Robust Power Handling: 0.1W per resistor and 0.75W total derated power at elevated temperatures up to 125°C.
• Gull Wing Termination: Ensures reliable solder joints for surface-mount (SMD) applications.
• Wide Voltage Range: Supports up to 100V, making it versatile for both low and medium-voltage designs.

GUS-QS8A-03-3922-JF Applications

This resistor network excels in:

• Precision Instrumentation: Voltage dividers, feedback networks, and sensor interfaces requiring stable resistance values.
• Industrial Control Systems: Isolated signal paths in PLCs, motor drives, and power supplies.
• Telecommunications: Impedance matching and filtering in RF and baseband circuits.
• Medical Electronics: Low-drift circuits where temperature stability is critical.
• Automotive (Non-Automotive Rated): Prototyping or non-safety-critical automotive subsystems.
