GUS-QS8A-02-4530-CA Description

The GUS-QS8A-02-4530-CA 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 453Ω resistance value and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±50ppm/°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 provide robust handling of moderate power loads, while the gull-wing termination ensures reliable solder joints in automated assembly processes.

GUS-QS8A-02-4530-CA Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog circuits.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained PCBs.
• Isolated Resistor Configuration (ISOL): Each of the 8 resistors operates independently, reducing crosstalk in multi-channel systems.
• High Power Density: 0.1W per resistor (0.75W total) enables efficient heat dissipation in dense layouts.
• Automation-Friendly: Tube packaging and 0.64mm terminal pitch streamline pick-and-place manufacturing.
• Non-Automotive Grade: Optimized for industrial, telecom, and instrumentation applications where PPAP compliance is not required.
