GQ0A025110DT Description

The GQ0A025110DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 10 isolated resistors, each with a 511Ω resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy in circuit designs. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) assembly, while the ±50ppm/°C temperature coefficient guarantees stable performance across a wide operating range of -70°C to +125°C. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is engineered for precision analog and digital systems.

GQ0A025110DT Features

• High Precision: 0.5% tolerance and ±50ppm/°C TCR for stable performance in temperature-variable environments.
• Robust Construction: Ceramic substrate and thin-film technology ensure durability and long-term reliability.
• Isolated Design: Independent resistors (ISOL circuit designator) prevent crosstalk, ideal for signal isolation.
• Compact Form Factor: 8.66mm × 6.02mm × 1.47mm dimensions with a 0.64mm terminal pitch, suitable for high-density PCB layouts.
• Wide Operating Range: Derated power up to 125°C, making it suitable for industrial and automotive-adjacent applications (though not PPAP or Automotive qualified).
• Surface-Mount Ready: Gull-wing terminals facilitate automated assembly processes.
