GUS-QS8A-03-3920-GB Description

The GUS-QS8A-03-3920-GB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 392Ω resistance value per resistor with a tight 2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient. Packaged in a 16-pin QSOP (Quarter-Small Outline Package) with gull-wing SMD termination, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) ideal for space-constrained designs. The network supports a 0.75W (3/4W) total power rating (0.1W per resistor) and operates reliably across a wide temperature range of 70°C to 125°C, with a maximum voltage rating of 100V. Its isolated circuit design (ISOL) ensures independent resistor performance, reducing crosstalk in critical circuits.

GUS-QS8A-03-3920-GB Features

• Precision Thin Film Technology: Delivers low noise, high stability, and excellent TCR performance (±25ppm/°C).
• Compact QSOP Package: Space-saving 16-pin gull-wing SMD design with 0.64mm terminal pitch for high-density PCB layouts.
• Isolated Resistor Network (ISOL): Each of the 8 resistors operates independently, ideal for signal isolation.
• Robust Power Handling: 0.75W total power dissipation (0.1W per resistor) with derated performance up to 125°C.
• Wide Voltage Range: Supports up to 100V, suitable for industrial and automotive-adjacent applications (non-automotive PPAP).
• Non-RoHS Compliant: May be preferred for legacy or specialized systems requiring specific material properties.

GUS-QS8A-03-3920-GB Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, DAC/ADC reference networks, and sensor conditioning.
• Signal Isolation: Buffering and impedance matching in communication interfaces (e.g., RS-485, CAN).
• Industrial Controls: PLCs, motor drives, and power supply feedback loops requiring stable resistance under thermal stress.
• Test & Measurement Equipment: Calibration circuits and instrumentation amplifiers where TCR stability is critical.
• Legacy Electronics: Military/aerospace systems or repair scenarios where RoHS compliance is not mandated.
