GUS-QS8A-02-1783-FB Description

The GUS-QS8A-02-1783-FB is a high-performance 8-resistor thin film network from TT Electronics/IRC, designed for precision applications requiring stable resistance values and tight tolerances. Encased in a 16-pin QSOP (QSOP-16) package, this surface-mount device (SMD) offers a 178K Ohm resistance per resistor with a 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring minimal resistance drift across operating conditions. Rated for 0.75W (3/4W) total power and 0.1W per resistor, it operates reliably within a temperature range of 70°C to 125°C, with a maximum voltage rating of 100V. Its isolated (ISOL) circuit design and gull-wing termination facilitate secure PCB mounting and efficient heat dissipation.

GUS-QS8A-02-1783-FB Features

• Precision Thin Film Technology: Delivers superior stability, low noise, and high accuracy (±1%) for critical circuits.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained designs.
• Robust Power Handling: Supports 0.75W total dissipation (0.1W per resistor) with derated performance up to 125°C.
• Low TCR (±50ppm/°C): Minimizes resistance variation under thermal stress, outperforming thicker film alternatives.
• Isolated Resistor Network: Each resistor operates independently, reducing crosstalk in multi-channel systems.
• Automotive-Grade Alternatives: While not automotive-qualified (PPAP: No), its reliability suits industrial and telecom applications.
