GUS-QS8A-02-1803-GG Description

The GUS-QS8A-02-1803-GG from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package integrates 8 isolated 180K Ohm resistors with a tight 2% tolerance and a low ±50ppm/°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, it is engineered for reliability in demanding circuits. The gull-wing termination and 0.64mm terminal pitch facilitate automated assembly, while the compact 4.9mm x 6.02mm x 1.47mm footprint optimizes board space.

GUS-QS8A-02-1803-GG Features

• Precision Thin Film Technology: Delivers superior accuracy and stability compared to thick-film alternatives.
• Isolated Resistor Design (ISOL): Each of the 8 resistors operates independently, ideal for multi-channel isolation.
• High Power Density: 0.75W total dissipation in a miniature QSOP package, outperforming similar-sized arrays.
• Extended Temperature Range: Derated operation up to 125°C ensures reliability in harsh environments.
• RoHS Non-Compliant: Suitable for legacy systems where lead-free compatibility is not required.
• Tube Packaging: Protects components during handling and supports automated pick-and-place processes.
