GQ8A018872GGT Description

The GQ8A018872GGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a ceramic QSOP package with 16 gull-wing terminals, offering a compact 4.9mm × 6.02mm × 1.47mm footprint and surface-mount compatibility. Each resistor provides a 88.7kΩ resistance with a tight 2% tolerance and a ±100ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Rated for 0.75W (3/4W) total power dissipation and 100V maximum voltage, it is ideal for high-reliability circuits requiring consistent performance under thermal stress.

GQ8A018872GGT Features

• Precision Thin-Film Technology: Delivers low noise and high accuracy (±2%) for sensitive analog/digital systems.
• Robust Ceramic Construction: Enhances thermal conductivity and mechanical durability in harsh environments.
• Isolated Network (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel designs.
• High Power Handling: 0.1W per resistor (0.75W total) outperforms standard arrays in power density.
• Wide Temperature Range: Stable performance from -70°C to +125°C (derated above 70°C).
• QSOP Gull-Wing Package: Facilitates automated PCB assembly with a 0.64mm terminal pitch.
