GQ8A0354R9JCT Description

The GQ8A0354R9JCT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications requiring stable resistance values and tight tolerances. Housed in a 16-pin QSOP ceramic package, this surface-mount device offers a 54.9Ω resistance per element with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across operating temperatures. The network is configured in an isolated (ISOL) circuit design, making it ideal for applications requiring independent resistor paths. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it delivers robust performance in compact designs.

GQ8A0354R9JCT Features

• Thin Film Technology: Provides superior stability, low noise, and precise resistance values compared to thick-film alternatives.
• Ceramic QSOP Package: Enhances thermal management and durability in harsh environments.
• Gull Wing Termination: Facilitates reliable surface-mount assembly and solder joint integrity.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, suitable for industrial and automotive-grade applications (though not PPAP or Automotive certified).
• Isolated Resistor Configuration: Each of the 8 resistors is electrically independent, enabling flexible circuit design.
• Compact Dimensions: 4.9mm (L) x 6.02mm (D) x 1.47mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D) for space-constrained PCBs.
