GUS-QS8A-02-4530-GA Description

The GUS-QS8A-02-4530-GA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low thermal drift. This 8-resistor isolated network features a 453Ω resistance per element with a tight 2% tolerance and a ±50ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). Encased in a compact 16-pin QSOP (QSOP-16) package, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and supports 100V maximum voltage, making it ideal for space-constrained, high-density PCB designs. The gull-wing termination ensures secure surface-mount (SMD) attachment, while its thin-film technology provides superior accuracy and stability compared to thick-film alternatives.

GUS-QS8A-02-4530-GA Features

• Precision Thin Film: Delivers low noise, high stability, and tight tolerance (±2%) for critical circuits.
• Isolated Design (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• High Power Handling: 0.75W total power (0.1W per resistor) with derating up to 125°C.
• Compact QSOP Package: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) footprint with 0.64mm terminal pitch for high-density layouts.
• Robust Construction: Gull-wing leads enhance mechanical durability and solder joint reliability.
• Wide Voltage Range: Supports up to 100V, suitable for industrial and automotive-grade applications (though non-automotive per PPAP).

GUS-QS8A-02-4530-GA Applications

• Signal Conditioning: Precision voltage dividers, feedback networks in op-amp circuits.
• Medical Electronics: Patient monitoring systems where low drift and accuracy are critical.
• Test & Measurement Equipment: Calibration circuits, sensor interfaces.
