GQ8A031691GAT Description

The GQ8A031691GAT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Housed in a 16-pin QSOP ceramic package, it features 1.69KΩ resistance per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. The isolated (ISOL) circuit design allows independent resistor operation, making it ideal for complex circuit configurations. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, this surface-mount device (SMD) delivers reliable performance in demanding environments. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration.

GQ8A031691GAT Features

• Precision Thin Film Technology: Ensures low noise and high accuracy (±25ppm/°C TCR).
• Ceramic QSOP Package: Offers superior thermal and mechanical stability compared to plastic alternatives.
• Isolated Resistor Network: Each of the 8 resistors operates independently, enabling flexible circuit designs.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) at derated temperatures up to 125°C.
• Compact & Robust: Dimensions of 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• Surface-Mount Gull Wing Terminals: Ensures reliable solder joints and compatibility with automated assembly processes.
