GUS-QS8A-01-2552-JA Description

The GUS-QS8A-01-2552-JA from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a 16-pin QSOP package with gull-wing SMD termination, this device offers a 25.5KΩ resistance per resistor with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. Its isolated (ISOL) circuit design provides independent resistors, making it ideal for applications requiring signal isolation. With a power rating of 0.75W (3/4W) total and 0.1W (1/10W) per resistor, it supports robust performance in compact designs. The 100V maximum voltage rating and thin-film technology enhance reliability in demanding environments.
