相对传统产品，三明治机构产品增加了高强度介质层。
The new product called sandwich-structure add high intensity layers . |
以上对比，表明三明治结构产品强度更高。
Above all , the sandwich-structure products are more stronger .
2．产品应用Product Application
三明治结构产品用于替代低容值常规X7R产品，如节能灯、LED灯、通用电源、工业控制、家电等要求元件具有较好抗折强度以保证产品可靠性的领域。
With better flexural strength to ensure product reliability, Sandwich MLCC is used to replace normal low capacitance X7R MLCCs, which applied to ESL,LED lamp, Power supply, Industrial control, Home appliance fields.
3．电容器及介质分类 Types of Capacitor and Dielectric Material
※X7R：此类介质材料的电容器为Ⅱ类电容器，具有较高的介电常数，容量比Ⅰ类电容器高，具有较稳定的温度特性，适用于容量范围广，稳定性要求不高的电路中，如隔直、耦合、旁路、鉴频等电路中。
※ X7R： material is a kind of material has high dielectric constant. The capacitor made of this kind material is considered as Class Ⅱ capacitor whose capacitance is higher than that of class Ⅰ. These capacitors are classified as having a semi-stable temperature characteristic and used over a wide temperature range, such in these kinds of circuits, DC-blocking, decoupling, bypassing, frequency discriminating etc.
