GQ8A031781DAT Description

The GQ8A031781DAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 1.78KΩ resistance value per resistor with a tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a ceramic QSOP package with 16 gull-wing terminals, it offers excellent thermal and mechanical stability. The isolated (ISOL) circuit design ensures minimal crosstalk, making it ideal for precision analog circuits. With a maximum voltage rating of 100V and a total power rating of 0.75W (0.1W per resistor), this component is suited for high-reliability applications.

GQ8A031781DAT Features

• High Precision: 0.5% tolerance and ±25ppm/°C TCR for stable performance.
• Robust Construction: Ceramic case and thin-film technology enhance durability and thermal performance.
• Isolated Design (ISOL): Minimizes interference between resistors, critical for sensitive circuits.
• Compact & Reliable: QSOP-16 package (4.9mm x 6.02mm x 1.47mm) with gull-wing leads for secure SMD mounting.
• Wide Operating Range: Supports -55°C to +125°C, derated up to 125°C.
• Low Power Dissipation: 0.1W per resistor (0.75W total) balances performance and thermal management.
