多芯组合无包封堆叠多层瓷介电容器
特征与应用
·由两个或多个多层片式瓷介电容器堆叠无包封,能获得2倍或3倍的容量,且节省了线路板的占用面积;
·介质为Ⅱ类瓷介,电容器容量体积比大;
l Class II Ceramic Dielectric, Large Capacitance Volume;
·有更低的ESR和ESL可确保高频开关电源的优良性能,在大电流高频环境下的性能远远优于铝电解电容或钽电解电容,能替代钽电容;
Lower ESR and ESL could ensure the nice-feature of High frequency switching power supply, such MLCC has more advanced performances than tantalum capacitors and aluminum capacitors in high volume & frequency environment, even it can instead of tantalum capacitors in some cases.
·无极性,安装方便,适合用作印制电路的表面贴装元件;
Non-polarity, easier for mounting, suit for surface mount component which has printed circuit;
·产品100%进行温度冲击和高温电负荷筛选;
Have experienced 100% Thermal Shock & High-Temperature Electron-Load Screening;
·主要用于DC-DC转换器、高容量放电电路、开关电源、滤波器、去耦装置等;
