GUS-QS8A-02-6491-FF Description

The GUS-QS8A-02-6491-FF from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a 16-pin QSOP package with gull wing termination, this surface-mount device offers a 6.49KΩ resistance per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient. Its isolated (ISOL) circuit design ensures independent resistor functionality, making it ideal for signal conditioning and voltage division. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates reliably across a wide temperature range of -70°C to +125°C, meeting demanding industrial and automotive-grade requirements (though not PPAP or Automotive certified). The compact 4.9mm x 6.02mm x 1.47mm footprint and ±0.1mm height tolerance enable high-density PCB layouts.

GUS-QS8A-02-6491-FF Features

• Precision Thin Film Technology: Delivers stable performance with ±50ppm/°C TCR and 1% tolerance for critical analog circuits.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) at 125°C max operating temperature, derated for reliability.
• Isolated Network (ISOL): Eight independent resistors in a single package, reducing board space versus discrete components.
• Robust Construction: QSOP package with gull wing leads ensures mechanical durability and ease of automated assembly.
• Wide Voltage Rating: Supports up to 100V, suitable for industrial power supplies and instrumentation.
