GUS-QS8A-01-4121-JB Description

The GUS-QS8A-01-4121-JB from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package features 4.12KΩ resistors with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating range of -70°C to +125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it delivers reliable power handling in compact designs. The isolated (ISOL) circuit design enhances signal integrity, while the gull-wing termination ensures robust solderability for automated assembly processes. Packaged in a tube, it is optimized for high-volume manufacturing.
