GUS-QS8A-02-8251-FA Description

The GUS-QS8A-02-8251-FA from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications in surface-mount circuits. With a resistance value of 8.25KΩ and a tight 1% tolerance, this component ensures reliable signal conditioning and voltage division in compact designs. The QSOP-16 package (4.9mm × 6.02mm × 1.47mm) features gull-wing terminations for robust solderability, while its ±50ppm/°C temperature coefficient guarantees stability across a wide operating range of -55°C to +125°C. Rated for 0.75W total power dissipation (0.1W per resistor), it supports moderate power handling with 100V maximum voltage rating. The isolated (ISOL) circuit design enhances signal integrity by minimizing crosstalk, making it ideal for noise-sensitive environments.

GUS-QS8A-02-8251-FA Features
