GUS-QS8A-03-5230-BA Description

The GUS-QS8A-03-5230-BA from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. With a 523Ω resistance value and an ultra-tight 0.1% tolerance, this QSOP-packaged device delivers exceptional accuracy and stability. Its ±25ppm/°C temperature coefficient ensures minimal resistance drift across a wide operating range of -70°C to +125°C, making it suitable for harsh environments. The isolated (ISOL) circuit design allows independent resistor operation, while the 0.75W (3/4W) total power rating (0.1W per resistor) supports robust performance in compact layouts.
