Yageo CQ MLCC Browse Inventory

Yageo’s CQ series MLCC high frequency performance (High Q) and ultra-low power consumption (Low ESR). They are suitable for RF applications, including power amplifiers, noise filtering, antenna tuning and impedance matching. CQ series operate in a temperature stable NPO dielectric range from 0201 to 0805 in size and 16V to 250V in narrow capacitance tolerance.

The rapid development of wireless and mobile communication systems require high transmission speed and high performance by minimizing device power consumption in the high frequency band. In response to increasing demand, Yageo has released its new CQ series, surface mount multilayer ceramic capacitors (SMD MLCCs), also known as high quality factor capacitors (high-Q capacitors). The CQ series adds copper inner electrodes and firing ceramic materials with excellent dielectric characteristics, providing lower dissipation and fewer self-heating problems compared to standard MLCCs.

The CQ 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 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 the UHF, SHF and microwave frequency bands.
