Series HQC

Hi Q C0G series MLCC, microwave multi-layer ceramic chip capacitor with a linear temperature coefficient, using paraelectric dielectric material, is heat stable. It is extremely stable and its capacitance is almost not affected by time, AC or DC signal.

        It has extremely low dielectric loss (or high Q) and low ESR.

        It is applied for RF microwave circuit with high demanding on Hi-Q and Low ESR.
