GUS-QS8A-02-3900-JF Description

The GUS-QS8A-02-3900-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount circuits. This 16-pin QSOP package features 8 isolated resistors, each with a 390Ω resistance, 5% tolerance, and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for reliability in demanding environments. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the compact 4.9mm × 6.02mm × 1.47mm footprint optimizes space efficiency.

GUS-QS8A-02-3900-JF Features

• Isolated Circuit Design (ISOL): Each of the 8 resistors operates independently, reducing crosstalk and improving signal integrity.
• Thin-Film Technology: Delivers superior accuracy, low noise, and excellent thermal stability compared to thick-film alternatives.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) supports robust performance in power-sensitive designs.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, with derated power up to 125°C.
• Compact QSOP Package: Ideal for high-density PCB layouts, with a 1.63mm seated height and gull-wing leads for automated assembly.
• Non-Automotive Grade: Suitable for industrial, telecom, and instrumentation applications where PPAP compliance is not required.
