GQ8A033480FBT Description

The GQ8A033480FBT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications requiring stable resistance and low thermal drift. Encased in a ceramic QSOP package, this 16-pin SMD component offers a 348Ω resistance per resistor with a tight 1% tolerance and an ultra-low ±25ppm/°C temperature coefficient. Its isolated (ISOL) circuit design ensures independent resistor functionality, making it ideal for signal conditioning, voltage division, and impedance matching. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably across a wide temperature range (-70°C to +125°C). The gull-wing termination and 0.64mm pitch facilitate robust surface mounting, while the ceramic construction enhances thermal stability and durability.
