GUS-QS8A-01-2550-JB Description

The GUS-QS8A-01-2550-JB from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications in surface-mount PCB assemblies. Encased in a compact 16-pin QSOP package, this 255 Ohm network offers a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature 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 is engineered for reliability in demanding environments. The isolated (ISOL) circuit design provides flexibility in circuit configurations, while the gull-wing termination ensures robust solder joint integrity. Packaged in tubes, it is optimized for automated assembly processes.
