GQ0A021073CT Description

The GQ0A021073CT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP device integrates 10 isolated resistors, each with a 107KΩ resistance value and an exceptional ±0.25% tolerance, ensuring minimal deviation in critical circuits. The ceramic case construction enhances thermal stability, while the ±50ppm/°C temperature coefficient guarantees reliable performance across a 70°C to 125°C operating range. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, it is ideal for precision analog and digital systems requiring tight resistance matching.

GQ0A021073CT Features

• High Precision: ±0.25% tolerance and ±50ppm/°C TCR for stable performance in temperature-variable environments.
• Robust Construction: Ceramic substrate and gull-wing termination ensure durability and ease of surface-mount (SMD) assembly.
• Isolated Design: Independent resistors (ISOL circuit designator) prevent crosstalk, suitable for multi-channel isolation.
• Compact Form Factor: 8.66mm × 6.02mm × 1.47mm dimensions with tight tolerances (±0.1mm height/length) save PCB space.
• Wide Operating Range: Supports -55°C to 125°C with derated power up to 125°C, exceeding standard industrial requirements.
