GUS-QS8B-02-4300-C Description

The GUS-QS8B-02-4300-C from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package features 15 resistors with a 430Ω resistance value, offering a tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power dissipation (0.05W per resistor), it operates reliably across a wide temperature range of 70°C to 125°C, with a maximum operating temperature of 125°C. Its gull-wing termination and 0.64mm terminal pitch ensure secure PCB mounting, while the compact 4.9mm × 6.02mm × 1.47mm footprint suits space-constrained designs.

GUS-QS8B-02-4300-C Features

• Precision Thin Film Technology: Delivers stable performance with low noise and high accuracy.
• High Power Handling: 0.75W total rating (distributed across 15 resistors) for robust operation.
• Automotive-Grade Alternatives: While not automotive-qualified, its 125°C max temperature and 100V max voltage rating make it suitable for industrial use.
• Compact QSOP Package: Ideal for high-density PCBs, with 16 gull-wing leads for reliable soldering.
• Non-RoHS Compliance: Suitable for legacy or specialized applications requiring non-compliant materials.
