GUS-QS8A-01-8660-JA Description

The GUS-QS8A-01-8660-JA from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package features isolated resistors with a 866Ω resistance value, 5% tolerance, and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this component is engineered for reliability in demanding circuits. Its gull-wing termination and 0.64mm terminal pitch facilitate easy soldering and high-density mounting.

GUS-QS8A-01-8660-JA Features

• Thin Film Technology: Delivers superior accuracy, low noise, and stability compared to thick-film alternatives.
• Isolated Resistor Network (ISOL): Each resistor operates independently, ideal for multi-channel signal conditioning.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), saving board space.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, suitable for industrial and automotive environments (though not PPAP/automotive-certified).
• Robust Power Handling: 0.75W total dissipation with derating up to 125°C.
• Non-RoHS Compliant: May be preferred for legacy or high-reliability systems requiring leaded soldering.

GUS-QS8A-01-8660-JA Applications

• Signal Isolation & Conditioning: Precision dividers, feedback networks, and sensor interfaces in instrumentation.
• Medical Electronics: Patient monitoring systems where stable resistance values are critical.
• Industrial Controls: PLCs, motor drives, and power supplies requiring high-temperature operation.
• Telecom Infrastructure: RF modules and baseband processing where space efficiency matters.
• Legacy Equipment Repair: Direct replacement for older QSOP resistor networks.
