GUS-QS8A-03-9530-CA Description

The GUS-QS8A-03-9530-CA 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 953Ω resistance and an ultra-tight 0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -55°C to +125°C, making it suitable for environments with thermal fluctuations. The 0.75W (3/4W) total power rating and 100V maximum voltage rating further enhance its reliability in power-sensitive designs.

GUS-QS8A-03-9530-CA Features

• Precision Thin Film Technology: Offers low noise and high stability for critical analog circuits.
• Isolated Resistor Configuration (ISOL): Each of the 8 resistors operates independently, reducing crosstalk in multi-channel systems.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained PCBs.
• Gull Wing Termination: Ensures robust solder joints and compatibility with automated assembly processes.
• Derated Power Handling: Maintains 0.1W per resistor up to 125°C, outperforming standard thick-film networks.
• Non-Automotive Grade: Optimized for industrial, medical, and instrumentation applications where precision is paramount.
