GQ8A021802GT Description

The GQ8A021802GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 8-resistor isolated network features an 18K Ohm resistance per element with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring minimal drift across its operating range. Encased in a ceramic QSOP package, it offers superior thermal management and durability. The 16-pin gull-wing SMD termination facilitates reliable surface mounting, while its 0.75W (3/4W) total power rating (0.1W per resistor) supports moderate power dissipation. Rated for 100V maximum voltage and 125°C maximum operating temperature, it is ideal for industrial and instrumentation use.

GQ8A021802GT Features

• Precision Thin Film Technology: Delivers stable performance with ±50ppm/°C TCR and 2% tolerance.
• Robust Ceramic QSOP Package: Enhances thermal conductivity and mechanical strength.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk.
• High Power Handling: 0.75W total (0.1W per resistor) at 70–125°C derated range.
• Surface-Mount Gull Wing Terminals: Ensures secure PCB attachment with 0.64mm pitch.
• Compact Dimensions: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1–0.2mm).
• Non-Automotive, Non-RoHS: Suitable for industrial applications without RoHS restrictions.
