GUS-QS8A-02-51R1-JF Description

The GUS-QS8A-02-51R1-JF from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision applications in surface-mount PCB assemblies. This thin-film resistor array features a 51.1Ω resistance value per resistor with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Encased in a 16-pin QSOP (QSOP-16) package, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) with gull-wing terminations for reliable soldering. Rated for 0.1W (1/10W) per resistor and 0.75W (3/4W) total power dissipation, it supports 100V maximum voltage, making it suitable for moderate-power circuits.

GUS-QS8A-02-51R1-JF Features

• Isolated Circuit Design (ISOL): Each resistor operates independently, eliminating crosstalk for signal integrity.
• Thin-Film Technology: Delivers superior accuracy, low noise, and stability compared to thick-film alternatives.
• High-Temperature Resilience: Operates reliably up to 125°C with derated power handling at elevated temperatures.
• Space-Efficient QSOP Package: Ideal for dense layouts with a 0.64mm terminal pitch and 1.63mm seated height.
• Robust Construction: Gull-wing leads ensure mechanical durability and ease of automated assembly.
• Non-Automotive/Non-PPAP: Optimized for industrial, telecom, and consumer electronics where PPAP compliance isn’t required.
