GQ8A013572FT Description

The GQ8A013572FT 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 35.7KΩ resistance value with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers excellent thermal stability and durability, making it suitable for harsh environments. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this component is engineered for reliability in precision circuits.

GQ8A013572FT Features

• Isolation-Centric Design: Labeled with "ISOL" circuit designator, ideal for isolation applications requiring minimal crosstalk.
• High Power Handling: 0.75W total power dissipation (0.1W per resistor) outperforms standard networks in compact footprints.
• Robust Construction: Ceramic case and thin-film technology ensure low noise, high accuracy, and long-term stability.
• Surface-Mount Optimized: Gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration in high-density designs.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power, suited for industrial and automotive-grade systems (though not PPAP/automotive-certified).
