Hi-Q Capacitor 0402
Description
The “High-Q-series” was designed for wireless communications and high frequency applications.
The “High-Q-Capacitors” have a class 1 dielectric ceramic and copper inner electrode. The class 1
dielectric ceramic used, HQM, is a very stable dielectric offering a temperature coefficient of
capacitance (TCC) of 0± 60ppm/°C. The higher conductivity of copper give a lower ESR. These
advantages mean a improved performance of matching circuits, lower power dissipation and less
energy absorption.
