GUS-QS8A-02-63R4-DC Description

The GUS-QS8A-02-63R4-DC 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 resistors, each with a 63.4 Ω resistance and a tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a 0.75W (3/4W) total power rating and ±50ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -70°C to +125°C. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB assembly, while the compact 4.9mm x 6.02mm x 1.47mm footprint optimizes space efficiency.

GUS-QS8A-02-63R4-DC Features

• Precision Thin Film Technology: Offers low noise and high stability for critical analog circuits.
• Isolated Resistor Design (ISOL): Each of the 8 resistors operates independently, reducing crosstalk in multi-channel systems.
• High Power Handling: 0.1W per resistor (0.75W total) with derating up to 125°C, suitable for thermally constrained environments.
• Robust Construction: 100V maximum voltage rating and ±0.1mm height/length tolerances ensure reliability in industrial applications.
• Non-Automotive Compliance: Ideal for industrial, telecom, and test equipment where PPAP and automotive certifications are not required.
