GUS-QS8A-03-5620-CB Description

The GUS-QS8A-03-5620-CB is a high-precision 8-resistor isolated network from TT Electronics/IRC, designed for demanding surface-mount applications. This thin-film resistor array offers a 562Ω resistance per element with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP package with gull-wing terminations, it features a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-density PCB designs.

GUS-QS8A-03-5620-CB Features

• Precision Performance: Thin-film technology delivers low noise and high accuracy (±0.25%), critical for analog signal conditioning.
• Robust Construction: Isolated (ISOL) circuit design prevents crosstalk, ideal for multi-channel systems.
• Thermal Stability: ±25ppm/°C TCR ensures minimal drift in harsh environments.
• Space-Saving: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) footprint with 0.64mm terminal pitch optimizes board space.
• Reliable Termination: Gull-wing leads facilitate secure soldering for automated assembly.
• Non-Automotive/Non-PPAP: Suitable for industrial and commercial applications where PPAP compliance isn’t required.
