GQ8A028200DT Description

The GQ8A028200DT from TT Electronics/IRC is a high-precision 8-resistor isolated network designed for demanding surface-mount applications. Built with thin-film technology on a ceramic substrate, it delivers 820Ω resistance per element with an exceptional ±0.5% tolerance and ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The QSOP-16 package (4.9mm × 6.02mm × 1.47mm) features gull-wing terminations with a 0.64mm pitch, optimized for automated assembly. With a 0.1W power rating per resistor (0.75W total) and 100V maximum voltage rating, this non-automotive, non-PPAP compliant network is ideal for precision analog and digital circuits requiring isolation and minimal drift.

GQ8A028200DT Features

• High Precision: ±0.5% tolerance and ±50ppm/°C TCR for stable performance in temperature-varying environments.
• Robust Construction: Ceramic case and thin-film technology ensure durability and low noise.
• Compact Design: QSOP-16 package (4.9mm × 6.02mm × 1.47mm) saves board space while supporting high-density layouts.
• Isolated Configuration: Independent resistors (ISOL designator) prevent crosstalk, critical for signal integrity.
• Wide Voltage Range: Supports up to 100V, suitable for industrial and instrumentation applications.
• Surface-Mount Ready: Gull-wing terminals with 0.64mm pitch facilitate reliable soldering and rework.

GQ8A028200DT Applications
