1. 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.

下面推荐了一些好的设计。
To layout the capacitors for the breakaway PC board, it should be noted that the amount of
mechanical stresses given depending on capacitor layout. The example below shows
recommendations for better design.

在沿着分拨线分拨电路板时,对产品施加的机械应力与使用的方法关系很大。分折电路板时片状元件受到的疲劳按照如下顺序增
大:分折、剪切、V型槽、穿孔。因此,贴装时应该考虑电路板的分拨过程。
When breaking PC boards along their perforations, the amount lf mechanical stress on the capacitors can vary
according to the method used. The following methods are listed in order from least stressful to most stressful:
push-back, silt, -grooving, and perforation. Thus, any ideal SMD capacitor layout must also consider the PCB
splitting procedure.

注意 Caution
①理想状况的焊锡高度为电容器厚度的1/3 ~1/2,如下图所示:
①The ideal condition is to have solder mass (fillet) controlled to 1/2 to 1/3of the thickness of the
capacitor, as shown below:

②过长的焊接时间会影响端头的可焊性, 焊接时间尽可能保持与推荐时间一致。
②Because excessive dwell times can detrimentally affect solderability, soldering duration should be kept as
close to recommended times as possible.

7.4 分拨电路板 Handling
Breakaway PC boards (splitting along perforations)
⑴.在电容器或其它贴装后,必须注意因电路板弯曲或变形带来的应力。
⑵.分拨电路板时必须使用专用的夹具,不可以用手拨断。
⑴.When splitting the PC board after mounting capacitors and other components, care is required so as not to
give any stresses of deflection or twisting to the board.
⑵.Board separation should not be done manually, but by using the appropriate devices.
7.5保存 Storage
⑴.在下列环境中保存产品:温度 5~40℃;湿度 ≤70% RH
⑵.产品自生产之日保存期为一年,产品使用之前请勿拆开编带。
⑶.编带拆开后,产品应在三个月内使用。
⑷.高介电常数电容器 (X7R,X5R,Y5V,X6S,X7T,X6T,X7S) 的容值随时间会逐渐减小,所以在电路设计时应充分考虑这一现象。容
值减小的电容器在150℃热处理1小时后容值会恢复到初试值。
⑴. Keep the storage environment conditions as following: Temperature: 5~40℃;Humidity: ≤70% RH
⑵. Don’t open the tape until the parts are to be used, and store them within one year since the date printed
on the reel.
⑶. Use the chips within 3 months after the tape is opened.
⑷. The capacitance value of high dielectric constant capacitors (X7R,X5R,Y5V,X6S,X7T,X6T,X7S) will gradually
decrease with the passage of time, so this should be taken into consideration in the circuit design. If such a
capacitance reduction occurs, a heat treatment of 150℃ for 1 hour will return the capacitance to its initial
level.
