GQ8A011003CAT Description

The GQ8A011003CAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 8-resistor isolated network features a 100K Ohm resistance per element with an exceptional ±0.25% tolerance and a low ±100ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Encased in a ceramic QSOP package, it offers superior thermal and mechanical stability, making it ideal for high-reliability environments. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, this 16-pin gull-wing SMD device is optimized for surface-mount assembly in compact PCB designs.

GQ8A011003CAT Features

• Precision Performance: ±0.25% tolerance and ±100ppm/°C TCR for stable operation in temperature ranges from 70°C to 125°C.
• Robust Construction: Ceramic case ensures durability and excellent heat dissipation, critical for high-power applications.
• High-Density Integration: QSOP-16 package (4.9mm x 6.02mm x 1.63mm) with 0.64mm pitch enables space-efficient designs.
• Isolated Circuit Design: "ISOL" configuration provides independent resistors, reducing crosstalk in sensitive analog/digital systems.
• Reliable Termination: Gull-wing leads ensure secure solder joints for automated PCB assembly.
• Non-Automotive Grade: Suitable for industrial, medical, and instrumentation applications where PPAP compliance is not required.
