GUS-QS8A-02-4640-CB Description

The GUS-QS8A-02-4640-CB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package features 8 isolated resistors, each with a 464 Ω resistance value and an ultra-tight 0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±50 ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -55°C to +125°C, making it suitable for environments with fluctuating thermal conditions. The 0.75W (3/4W) total power rating and 100V maximum voltage rating further enhance its reliability in power-sensitive designs.

GUS-QS8A-02-4640-CB Features

• Precision Thin Film Technology: Delivers low noise and high stability for critical analog applications.
• Isolated Resistor Configuration (ISOL): Each of the 8 resistors operates independently, ideal for multi-channel isolation.
• Compact QSOP Package: Measures just 4.9mm (L) x 6.02mm (D) x 1.47mm (H), saving PCB space in dense layouts.
• Gull Wing Termination: Ensures robust solder joints for surface-mount assembly.
• Derated Power Handling: Maintains 0.1W per resistor up to 125°C, outperforming standard thick-film networks.
• Strict Tolerances: ±0.1mm (length/height) and ±0.2mm (depth) mechanical tolerances for consistent placement.

GUS-QS8A-02-4640-CB Applications
