GQ8A036490GGT Description

The GQ8A036490GGT is a high-precision 8-resistor thin film network from TT Electronics/IRC, designed for surface-mount applications requiring stable performance in demanding environments. Encased in a ceramic QSOP package, it offers a 649Ω resistance per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across its operating range of -70°C to +125°C. The 16-pin gull-wing termination facilitates reliable PCB mounting, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating balance compactness with robust thermal handling.

GQ8A036490GGT Features

• Isolated Circuit Design (ISOL): Each resistor operates independently, ideal for precision signal conditioning.
• Ceramic QSOP Package: Enhances thermal stability and mechanical durability compared to plastic alternatives.
• Thin Film Technology: Delivers superior accuracy, low noise, and long-term reliability versus thick film networks.
• High Voltage Rating (100V): Suitable for industrial and telecom applications requiring voltage isolation.
• Strict Dimensional Tolerances: ±0.1mm (length/height) and ±0.2mm (depth) ensure consistent PCB fit.
• Non-Automotive (PPAP No): Optimized for commercial/industrial use, avoiding automotive-grade cost premiums.
