GUS-QS8A-02-1691-JA Description

The GUS-QS8A-02-1691-JA 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 SMD termination, this device offers a 1.69KΩ resistance per resistor with a 5% tolerance and a ±50ppm/°C temperature coefficient. Its 0.75W (3/4W) total power rating and 0.1W per resistor ensure reliable operation in demanding environments. The isolated (ISOL) circuit design enhances signal integrity, while the 100V maximum voltage rating and 125°C maximum operating temperature make it suitable for industrial and automotive-adjacent applications (though not PPAP or Automotive certified).

GUS-QS8A-02-1691-JA Features

• Thin Film Technology: Delivers superior stability, low noise, and tight TCR (±50ppm/°C).
• Compact QSOP Package: Measures 4.9mm (L) x 6.02mm (D) x 1.47mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D).
• High Power Density: 0.75W total dissipation in a miniature footprint, ideal for space-constrained designs.
• Isolated Resistors: Independent resistors reduce crosstalk, critical for analog signal conditioning.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ensuring reliability in thermal extremes.
• RoHS Non-Compliant: Suitable for legacy systems where lead-free alternatives are incompatible.

GUS-QS8A-02-1691-JA Applications

• Precision Instrumentation: Signal amplification, filtering, and divider networks in test equipment.
