GUS-QS8A-02-4750-JB Description

The GUS-QS8A-02-4750-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 8-resistor isolated network features a 475Ω resistance value per resistor with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Packaged in a 16-pin QSOP (Quarter Small Outline Package) with gull-wing SMD terminations, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) ideal for space-constrained designs. The 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for moderate-power applications, while its 100V maximum voltage rating ensures reliability in high-voltage environments.

GUS-QS8A-02-4750-JB Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and excellent thermal stability compared to thick-film alternatives.
• Isolated Circuit Design (ISOL): Each resistor operates independently, eliminating crosstalk and enabling flexible circuit configurations.
• High-Temperature Resilience: Rated for 125°C maximum operating temperature, making it suitable for industrial and automotive-adjacent applications (though not PPAP or Automotive certified).
• Precision Gull-Wing Terminations: 0.64mm pitch ensures reliable solderability and compatibility with automated PCB assembly processes.
• Robust Construction: Tight tolerances on dimensions (±0.1mm height/length, ±0.2mm depth) ensure consistent placement and mechanical stability.
• Non-RoHS Compliant: May be preferred for legacy or specialized applications requiring leaded components.
