MLCC exhibits the world’s highest Q value for UHF band
A Q 01005 MLCC, claimed to exhibit the world’s highest Q value for UHF band applications, has been introduced by AVX. The CU10 01005, which is part of the company’s CU series of low ESR C0G (NP0) MLCCs, exhibits typical Q values of 290 at 1GHz for a 4pF capacitance.
The device is suitable for reducing power consumption and improving battery efficiency in the high frequency power amplifier circuits within multifunctional and multiband RF communication devices. Such devices include smartphones, tablets, handheld scanners, camera sensor modules and telecomms equipment.
The CU MLCCs feature low-resistance internal copper electrodes and interior structures that have been optimised to reduce resistance. The devices also exhibit highly accurate and evenly distributed capacitances spanning 0.5 to 22pF, which, combined with the outstanding ESR, effectively mitigates impedance mismatching between circuits and subsequently preserves both power and battery life.
The CU10 01005 is available in 16V ratings and with capacitance values spanning 0.5 to 22pF. Intended for use in temperatures ranging from -55 to +125°C, the CU MLCCs are lead-free compatible and RoHS compliant, and are supplied with plated Ni/Sn terminations on both 4 and 8mm 7” reels.
“Exhibiting the world’s highest Q value, the subminiature CU10 MLCCs allow RF design engineers to achieve a meaningful reduction in the power consumption of ultra high frequency circuits, which subsequently improves battery efficiency,” said Kazushige Takamori, Marketing Manager, AVX. “Consequently, the CU10 provides engineers with an effective and robust solution for satisfying the continual consumer demand for extended battery lifetimes in smartphones and other devices that must continuously support high speed and high data rate communications.”
