GQ0A031131DBT Description

The GQ0A031131DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerance, stability, and isolation. This 10-resistor array features a 1.13KΩ resistance value per resistor with an exceptional ±0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). Housed in a 20-pin QSOP ceramic package, it offers 1W total power dissipation (0.1W per resistor) and 100V maximum voltage rating, making it suitable for precision analog and digital circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while the isolated (ISOL) circuit configuration enhances signal integrity in multi-channel systems.

GQ0A031131DBT Features

• High Precision: ±0.5% tolerance and ±25ppm/°C TCR for stable performance in critical circuits.
• Robust Construction: Ceramic case ensures durability and thermal stability, with a rectangular QSOP package (8.66mm × 6.02mm × 1.47mm) and tight dimensional tolerances (±0.1mm height/length).
• Isolated Design: Independent resistors (ISOL configuration) minimize crosstalk, ideal for multi-signal applications.
• Wide Operating Range: Rated for 125°C maximum temperature and derated power up to 125°C, suitable for industrial environments.
• Thin-Film Technology: Delivers low noise, high accuracy, and long-term reliability compared to thick-film alternatives.
• Automation-Friendly: Gull-wing leads and 0.64mm pitch enable seamless SMD placement.
