GQ8A031821JFT Description

The GQ8A031821JFT 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 1.82KΩ resistance per resistor with a 5% 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 secure surface-mount (SMD) attachment, with a compact footprint of 4.9mm (L) × 6.02mm (D) × 1.47mm (H). Its isolated (ISOL) circuit design allows independent resistor operation, while the 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding environments. Packaged in a tube, it is ideal for prototyping and automated assembly.
