GQ8A025111FAT Description

The GQ8A025111FAT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a ceramic QSOP package, it offers a 5.11KΩ resistance per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. The device features 16 gull-wing terminals for reliable surface-mount (SMD) assembly, with a compact footprint of 4.9mm (L) × 6.02mm (D) × 1.47mm (H). Its isolated (ISOL) circuit design allows independent resistor operation, making it suitable for complex circuit configurations. Rated for 0.1W per resistor and 0.75W total power dissipation, it supports 100V maximum voltage, ideal for high-density PCB designs.
