GQCA033480DBT Description

The GQCA033480DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP package features 12 isolated resistors, each with a 348Ω resistance value and an ultra-tight ±0.5% tolerance. Built with ceramic substrate and thin-film technology, it ensures excellent stability, low noise, and high reliability under varying thermal conditions. With a ±25ppm/°C temperature coefficient, it maintains consistent performance across a wide operating range of -70°C to +125°C. The gull-wing termination and surface-mount design facilitate automated PCB assembly, while its 100V maximum voltage rating and 1W total power dissipation make it suitable for precision analog and digital circuits.

GQCA033480DBT Features
