GQ8A021103JBT Description

The GQ8A021103JBT 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 110K Ohm resistance per resistor with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The device features 16 gull-wing terminals for reliable surface-mount (SMD) assembly, with a compact footprint (4.9mm x 6.02mm x 1.47mm) and a 0.64mm terminal pitch, making it suitable for space-constrained designs. Its isolated (ISOL) circuit design minimizes crosstalk, while the 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating ensure robustness in demanding environments.
