GUS-QS8A-03-1203-DA Description

The GUS-QS8A-03-1203-DA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated 120KΩ resistors with a tight tolerance of ±0.5% and a low temperature coefficient of ±25ppm/°C, ensuring stable performance across a wide temperature range (70°C to 125°C). With a power rating of 0.75W (3/4W) total and 0.1W (1/10W) per resistor, it supports robust operation in compact designs. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while its thin-film technology delivers superior accuracy and long-term reliability compared to thick-film alternatives.

GUS-QS8A-03-1203-DA Features

• Precision Performance: 0.5% tolerance and ±25ppm/°C TCR for critical analog/digital circuits.
• High Power Handling: 0.75W total (0.1W per resistor) at 125°C maximum operating temperature.
• Compact & Robust: QSOP package (4.9mm x 6.02mm x 1.47mm) with 16 gull-wing leads for space-constrained PCBs.
• Isolated Design: 8 independent resistors (ISOL circuit) for flexible circuit configurations.
• Thin-Film Technology: Low noise, excellent stability, and repeatability for precision applications.
• Wide Voltage Rating: Supports up to 100V maximum voltage, suitable for industrial and instrumentation use.

GUS-QS8A-03-1203-DA Applications

Ideal for:

• Precision voltage dividers in test/measurement equipment.
• Signal conditioning in industrial automation and control systems.
• Feedback networks for op-amps and ADCs/DACs.
• Medical electronics where stability and accuracy are critical.
• Aerospace/defense systems requiring high reliability under thermal stress.

Conclusion of GUS-QS8A-03-1203-DA

The GUS-QS8A-03-1203-DA excels in applications demanding high precision, thermal stability, and compact form factors. Its thin-film isolation, robust power rating, and gull-wing SMD compatibility make it a superior choice over thicker-film networks or discrete resistors. While not RoHS-compliant, its performance in harsh environments (e.g., 125°C operation) and low TCR drift justify its use in specialized industrial, medical, and aerospace designs. Packaged in tubes for automated assembly, it balances manufacturability with elite electrical characteristics.
