GQ8A031050GGT Description

The GQ8A031050GGT 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 105 Ohm resistance per resistor with a tight 2% tolerance and a low ±25ppm/°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). Rated for 0.1W per resistor and 0.75W total power dissipation, it supports 100V maximum voltage, making it suitable for demanding circuits requiring isolation (ISOL designation). Packaged in tubes, it is ideal for automated PCB assembly.
