GQ8A034992FBT Description

The GQ8A034992FBT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Housed in a 16-pin QSOP ceramic package, it features 49.9K Ohm resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. The isolated (ISOL) circuit design allows independent resistor functionality, making it ideal for signal conditioning and voltage division. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, this surface-mount device (SMD) offers reliability in demanding environments. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration.
