GUS-QS8A-01-3090-JA Description

The GUS-QS8A-01-3090-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 8-resistor isolated network features a 309Ω resistance value per resistor with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Encased in a compact 16-pin QSOP (QSOP-16) package, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for demanding circuit designs requiring isolation and reliability.

GUS-QS8A-01-3090-JA Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and excellent thermal stability compared to thick-film alternatives.
• High-Density Packaging: Compact 4.9mm (L) × 6.02mm (D) × 1.47mm (H) footprint with 0.64mm terminal pitch, ideal for space-constrained designs.
• Robust Construction: Gull-wing termination ensures secure surface-mount attachment, while the QSOP case enhances mechanical durability.
• Wide Temperature Range: Operates reliably from -70°C to +125°C (derated power), suited for industrial and automotive-grade environments (though not PPAP or Automotive certified).
• Isolated Network (ISOL): Each resistor is electrically isolated, providing flexibility in circuit design for signal conditioning, pull-up/down networks, or voltage division.
