MLCCs For Low-power Mobile Telecommunications


TTI Europe is now stocking the Yageo’s CQ series surface mount multilayer ceramic capacitors (SMD MLCCs) for use in applications with high frequencies from 500MHz to 10GHz. The devices claim to offer improved low power consumption in the high frequency band for mobile telecommunications.

Benefiting from ultra-low power consumption for mobile telecommunications, low ESR (Equivalent Serial Resistance), low ESL (Equivalent Serial Inductance), and high SRF (Self Resonant Frequency) in the UHF, SHF and microwave frequency bands, CQ series products are suitable for RF applications, including power amplifiers, noise filtering, antenna tuning and impedance matching.

The Yageo’s CQ series SMD MLCCs are also known as high quality factor capacitors (high-Q capacitors). The devices add copper inner electrodes and firing ceramic materials with excellent dielectric characteristics, providing lower dissipation and fewer self-heating problems compared to standard MLCCs, according to the firm.

They operate in a temperature stable NPO dielectric range from 0201 to 0805 in size and 16V to 250V in narrow capacitance tolerance. Typically used in applications with high frequencies from 500MHz to 10GHz, the components also benefit from a high withstanding voltage.
