GQ8A0249R9FCT Description

The GQ8A0249R9FCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 49.9Ω resistance value with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. Housed in a 16-pin QSOP ceramic package, it offers superior thermal stability and mechanical robustness, making it ideal for high-reliability environments. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is engineered for precision analog and digital circuits requiring minimal drift and high isolation.

GQ8A0249R9FCT Features

• Isolation-Centric Design: Optimized for ISOL (isolation) applications, reducing crosstalk in multi-channel systems.
• Ceramic QSOP Package: Enhances thermal dissipation and durability compared to plastic alternatives.
• Thin-Film Technology: Delivers low noise, high accuracy, and excellent long-term stability.
