GQ8A024990CT Description

The GQ8A024990CT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Housed in a 16-pin QSOP ceramic package, it offers 499Ω resistance per element with an exceptional ±0.25% tolerance and ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range (70°C to 125°C). The isolated (ISOL) circuit design provides independent resistors, making it ideal for precision analog circuits. With a 0.75W total power rating (0.1W per resistor) and 100V maximum voltage rating, this surface-mount network delivers reliability in compact designs.

GQ8A024990CT Features

• High Precision: Tight 0.25% tolerance and thin film technology for low noise and drift.
• Robust Construction: Ceramic case ensures thermal stability and durability.
• Space-Efficient: QSOP gull-wing package (4.9mm x 6.02mm x 1.47mm) optimizes PCB real estate.
• Isolated Resistors: Independent elements (ISOL design) for flexible circuit integration.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power.
• Low TCR: ±50ppm/°C minimizes resistance shift under thermal stress.
