Yageo Corporation has introduced the automotive grade high frequency AQ series with the temperature stable NPO dielectrics of multi-layer ceramic capacitors (MLCC). The first released range covers size 0603, capacitance range: 0.2pF ~ 100pF with 50V rated voltage.

Featuring excellent temperature characteristics and a narrow tolerance of capacitance, the AQ series capacitors apply in-house designs concepts to both material and processing. The development demonstrates Yageo's leading position in innovation and R&D, as well as the firm's commitment to meeting customer's needs.

High-Q capacitors, also known as high quality factor capacitors, provide high quality factor (low dielectric loss), low power dissipation and are more efficient than standard MLCCs. The 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 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 frequency bands. They are ideal for high frequency applications such as impedance matching, decoupling, and resonance circuits.

To reach an even higher quality level, longer life, and superior reliability, approaches adopted include high quality raw materials, an advanced and dedicated production line and tightened processing control. In addition entire in-line and outgoing automatic checks are adopted on top of the existing production standards.

Production part approval process (PPAP) documents are ready for AQ series items. AQ series is RoHS compliant too and with improved thermal and mechanical robustness. This offers customers a wider variety of choices and solutions in order to meet various application demands and requirements.
