High Quality Factor NPO MLCC for High Frequency Applications
High-Q capacitors, also known as high quality factor capacitors,
provide high quality factor (low dielectric loss), low power dissipation, and better efficiency than standard MLCCs. The CQ-/AQ- series
high frequency MLCCs are typically used in applications with high frequencies from 500MHz to 10GHz. With improved low power consumption
for mobile telecommunications the CQ-/AQ- series has copper inner electrodes that allow for low ESR (Equivalent Serial Resistance),
low ESL (Equivalent Serial Inductance), and high SRF (Self Resonant Frequency) in UHF(300MHz-3GHz), SHF(3GHz-30GHz) and
microwave frequen-cy bands. They are ideal for high frequency applications such as impedance matching, decoupling, and resonance circuits.
The CQ series capacitors are offered in EIA case sizes from 01005 to 0805 and available in temperature stable NPO dielectrics with a
capacitance range of 0.1 to 100pF, and rated voltage up to 250V. The development demonstrates Yageo’s leading position in innovation
and R&D, as well as the firm’s commitment to meeting customer’s needs.
Just like Yageo’s other automotive grade MLCCs AC and AS, Yageo treats AEC-Q200 criteria as the basic quality requirements for its
AQ series MLCC. To reach even higher quality level, longer life, and more superior reliability, the approaches including high quality
raw material, advanced and dedicated production line, tightened processing control, and entire in line and outgoing automatic check
are adopted on top of the existing production standards. Production part approval process (PPAP) documents are ready for AQ series items.
As all other Yageo’s MLCC series, AQ series is RoHS compliant too and with improved thermal and mechanical robustness.
