GUS-QS8A-01-1781-JA Description

The GUS-QS8A-01-1781-JA from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications in surface-mount circuits. Encased in a 16-pin QSOP package, it offers a 1.78KΩ resistance per resistor with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.1W per resistor, this isolated network supports robust operation in compact designs. Its 100V maximum voltage rating and gull-wing termination make it suitable for automated PCB assembly, while the thin-film technology delivers superior accuracy and reliability compared to thick-film alternatives.

GUS-QS8A-01-1781-JA Features

• High-Density Integration: 8 resistors in a compact QSOP-16 package (4.9mm × 6.02mm × 1.47mm) save board space.
• Precision Performance: Thin-film construction ensures low noise and tight tolerance (±5%), ideal for signal conditioning.
• Thermal Stability: Operates reliably from 70°C to 125°C with derated power, suited for harsh environments.
• Automation-Friendly: Gull-wing leads and 0.64mm terminal pitch enable seamless surface-mount assembly.
• Isolated Design: Each resistor is electrically isolated (ISOL circuit designator), providing design flexibility.
• RoHS Non-Compliant: Suitable for legacy or specialized applications where RoHS restrictions do not apply.

GUS-QS8A-01-1781-JA Applications

This resistor network excels in:

• Analog Signal Processing: Voltage dividers, DAC/ADC interfaces, and sensor calibration circuits.
• Industrial Controls: PLCs, motor drives, and power management systems requiring stable resistance under thermal stress.
• Test & Measurement Equipment: Precision instrumentation where low TCR (±100ppm/°C) minimizes drift.
• Telecommunications: RF modules and filtering networks benefiting from thin-film accuracy.
• Legacy Electronics: Non-RoHS compliant designs needing high reliability.
