GUS-QS8A-02-2550-FF Description

The GUS-QS8A-02-2550-FF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 8-resistor isolated network features a 255Ω resistance value per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP (QSOP) package with gull-wing terminations, it offers excellent space efficiency and solderability for automated assembly processes. The device supports a maximum voltage rating of 100V and delivers a total power rating of 0.75W (3/4W), with 0.1W (1/10W) per resistor, making it suitable for demanding analog and digital circuits.

GUS-QS8A-02-2550-FF Features

• Precision Thin Film Technology: Delivers high accuracy (±1%) and low TCR (±50ppm/°C) for stable performance in temperature-sensitive applications.
• Isolated Resistor Network (ISOL): Each of the 8 resistors is electrically isolated, providing flexibility in circuit design.
• Robust Power Handling: Supports 0.75W total power dissipation (0.1W per resistor) with derating up to 125°C.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained designs.
• Automated Assembly-Friendly: Gull-wing terminations and 0.64mm terminal pitch ensure reliable solder joints in high-volume SMT processes.
• Non-Automotive, Non-PPAP: Suitable for industrial, telecom, and instrumentation applications where automotive compliance is not required.
