MLCCs target UHF band applications
The first part number of the latest CU series ultralow ESR C0G (NP0) MLCCs, the CU10 01005 MLCC, exhibits typical Q values of 290 at 1 GHz for a 4 pF capacitance, which makes it ideal for reducing power consumption and improving battery efficiency in the high frequency power amplifier circuits within multifunctional and multiband RF communication devices, including: smartphones, tablets, handheld scanners, camera sensor modules, and telecommunications equipment.
The CU series ultralow ESR MLCCs feature low-resistance internal copper electrodes and interior structures that have been carefully optimized to reduce resistance. The series also exhibits highly accurate and evenly distributed capacitances spanning 0.5 pF to 22 pF, which, combined with outstanding ESR, effectively mitigates impedance mismatching between circuits and subsequently preserves both power and battery life.
“Exhibiting the world’s highest Q value, the new 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 at AVX.
The 01005 CU10 ultralow ESR MLCCs are available in 16 V ratings and with capacitance values spanning 0.5 pF to 22 pF. Intended for use in temperatures spanning -55°C to +125°C, CU series MLCCs are lead-free compatible and RoHS compliant, and are supplied with plated Ni/Sn terminations on both 4-mm and 8-mm 7-inch reels. Lead time for the CU10 is 12 weeks, and the second part number of the series, the CU01 0201 MLCC, is expected to be introduced to the market later this year.
