GQCA0184R5GT

GQCA0184R5GT Description

The GQCA0184R5GT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 24-pin QSOP (Quarter Small Outline Package) device integrates 12 isolated resistors, each with a 84.5Ω resistance value and a tight 2% tolerance. The ceramic case ensures excellent thermal stability, while the thin-film technology delivers low noise and high reliability. With a ±100ppm/°C temperature coefficient, it maintains consistent performance across a wide temperature range (70°C to 125°C). Rated for 100V maximum voltage and 0.1W power dissipation per resistor (1W total), this network is ideal for precision analog and digital circuits.

GQCA0184R5GT Features

• High Isolation: Designed with ISOL (isolated) circuit topology, minimizing crosstalk between resistors.
• Robust Construction: Ceramic substrate enhances thermal dissipation and mechanical durability.
• Precision Performance: ±100ppm/°C TCR and 2% tolerance ensure stability in varying environments.
