GUS-QS8A-02-39R0-FD Description

The GUS-QS8A-02-39R0-FD from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision applications. This thin-film resistor array features a 39 Ohm resistance value with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP package with gull-wing SMD termination, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and a maximum voltage rating of 100V. Its isolated circuit design (ISOL) makes it ideal for applications requiring individual resistor independence. The rectangular package (4.9mm x 6.02mm x 1.47mm) with a 0.64mm terminal pitch ensures compatibility with high-density PCB layouts.

GUS-QS8A-02-39R0-FD Features

• Precision Thin Film Technology: Delivers high accuracy (±1%) and low TCR (±50ppm/°C) for stable performance.
• Isolated Resistor Network (ISOL): Each of the 8 resistors operates independently, eliminating crosstalk.
• Robust Power Handling: 0.75W total power dissipation (0.1W per resistor) at 125°C maximum operating temperature.
• Compact QSOP Package: Space-saving 16-pin SMD design (4.9mm x 6.02mm) with gull-wing leads for reliable soldering.
• Wide Voltage Rating: Supports up to 100V, suitable for industrial and automotive-grade circuits (though not PPAP/automotive certified).
• Non-RoHS Compliant: May be preferred for legacy or specialized applications requiring non-compliant materials.
