GQ8A033001FT Description

The GQ8A033001FT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Encased in a ceramic QSOP package, it offers a 3K Ohm resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -55°C to +125°C. The 0.75W (3/4W) total power rating and 0.1W per resistor derating up to 125°C make it suitable for power-sensitive designs. Its 100V maximum voltage rating and 16-pin gull-wing SMD termination provide robust connectivity in compact PCB layouts.

GQ8A033001FT Features

• Isolation-Centric Design: Labeled with "ISOL" circuit designator, ideal for galvanic isolation in analog/digital systems.
• Ceramic QSOP Package: Enhances thermal stability and durability compared to plastic alternatives.
• Thin Film Technology: Delivers superior accuracy (±1%) and low TCR (±25ppm/°C) for precision circuits.
• High-Density Integration: 8 resistors in a 4.9mm x 6.02mm footprint (±0.1mm length/depth tolerance) with 0.64mm pitch, saving board space.
• Derated Power Handling: Maintains 0.1W/resistor up to 125°C, outperforming standard networks in high-temperature environments.
• Non-Automotive, Non-RoHS: Suitable for industrial and military applications where RoHS compliance is not mandated.
