GUS-QS8A-03-4642-FB Description

The GUS-QS8A-03-4642-FB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device features 8 isolated resistors, each with a 46.4kΩ resistance value and a tight 1% tolerance. With a power rating of 0.75W (3/4W) total and 0.1W (1/10W) per resistor, it delivers reliable performance in compact designs. The ±25ppm/°C temperature coefficient ensures stability across a wide operating range of -55°C to +125°C, making it suitable for demanding environments. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the 1.47mm low-profile height optimizes space efficiency.
