GUS-QS8A-02-8251-FF Description

The GUS-QS8A-02-8251-FF from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. It features an 8.25KΩ resistance value per resistor 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. Packaged in a 16-pin QSOP with gull wing terminations, this surface-mount device (SMD) offers a compact footprint (4.9mm x 6.02mm x 1.47mm) with a 0.64mm terminal pitch, ideal for space-constrained PCB designs. The network is rated for 0.75W total power dissipation (0.1W per resistor) and supports 100V maximum voltage, making it suitable for demanding analog and digital circuits.

GUS-QS8A-02-8251-FF Features

• Precision Thin Film Technology: Delivers high accuracy (±1%) and low TCR (±50ppm/°C) for stable operation in varying environments.
• Robust Construction: QSOP package with gull wing leads ensures reliable surface-mount assembly and mechanical durability.
• Isolated Resistors (ISOL): Each of the 8 resistors is electrically isolated, providing design flexibility in circuit partitioning.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, suitable for industrial and automotive-grade applications (though not PPAP/automotive certified).
• High Power Handling: 0.75W total power rating (0.1W per resistor) outperforms similar networks in power density.
• Compact Dimensions: 4.9mm length, 6.02mm depth, and 1.47mm height enable high-density PCB layouts.
