GUS-QS8B-03-6491-JF Description

The GUS-QS8B-03-6491-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 integrates 15 resistors, each with a 6.49KΩ resistance value and a tight ±5% tolerance, ensuring consistent performance across demanding environments. With a 0.75W (3/4W) total power rating and ±25ppm/°C temperature coefficient, this network delivers stable operation under varying thermal conditions, making it suitable for high-reliability designs. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while its compact dimensions (4.9mm x 6.02mm x 1.47mm) optimize space efficiency.

GUS-QS8B-03-6491-JF Features

• Thin-Film Technology: Offers superior stability, low noise, and precision compared to thick-film alternatives.
• High Power Handling: 0.05W per resistor (0.75W total) with derated performance up to 125°C.
• Wide Voltage Range: Supports up to 100V, ideal for industrial and automotive-grade applications (though not PPAP/automotive-certified).
• Robust Construction: QSOP package with rectangular shape and tight tolerances (±0.1mm height, ±0.2mm depth) for consistent mounting.
• Non-RoHS Compliance: Suitable for legacy or specialized systems requiring leaded components.

GUS-QS8B-03-6491-JF Applications
