GQ8A031911JGT Description

The GQ8A031911JGT 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 1.91KΩ resistance per resistor with a 5% tolerance and a ±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) 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 ideal for signal conditioning and impedance matching. Rated for 0.1W per resistor (0.75W total), it supports 100V maximum voltage, suitable for industrial and telecom environments.
