貼片鋁電解電容器常用的有片狀多層陶瓷電容器、高頻圓柱狀電容器、片狀絳綸電容器、片狀電解電容器、片狀鉭電解電容器、片狀微調電容器等。在電路設計中應用廣泛使用，在貼片狀電容器使用中有哪些注意事項，電解電容廠家帶您一探究竟。

　　Chip aluminum electrolytic capacitors commonly used are multi-layer ceramic capacitor, high-frequency cylindrical capacitor, flake polyester capacitor, sheet electrolytic capacitor, tantalum electrolytic capacitor, chip trimming capacitor and so on. It is widely used in circuit design. What precautions should be taken in the use of SMC.

　　(1)電容器的工作電壓必須低于額定電壓，不得超過額定電壓使用。例如：工作電壓為12V時，可選額定電壓16～25V；工作電壓為5v時，可選6～10V；工作電壓為3.3V時，可選4～6V。

　　The working voltage of the capacitor must be lower than the rated voltage and should not exceed the rated voltage. When the rated voltage is between 3V and 12V, the rated voltage is between 3V and 12V; for example, when the rated voltage is between 3V and 12V, the working voltage is between 3V and 12V; for example, the rated voltage is 6v-12v.

　　另外，電容器的電容量還與耐壓值有關。例如：片狀鉭電容耐壓4～50V，0.1～4.7μF小容量電容有額定電壓為50V的，而10pF以上、耐壓值高于25V的就很少見到。因此，在進行電路設計時應引起注意。

　　In addition, the capacitance of the capacitor is also related to the withstand voltage value. For example: sheet tantalum capacitor withstand voltage 4 ~ 50V, 0.1 ~ 4.7 μ f small capacity capacitor has rated voltage of 50V, but more than 10PF, withstand voltage value higher than 25V is rarely seen. Therefore, attention should be paid to the circuit design.

　　(2)片狀電容器可以大電壓替代小電壓。例如：電路需要一個10V的1UF電容，可以用16V的1UF電容替代。

　　The chip capacitor can replace the small voltage with high voltage. For example: the circuit needs a 10V 1uF capacitor, which can be replaced by a 16V 1uF capacitor.

　　(3)應合理地選擇電容器精度及材料類別。市售的片狀電容器的精度在0.01μF以下的，其精度可達J級(±5%)；在0.01μF以上，則J級較少，以K級(±lO%)居多；在0.1μF以上，則以M級(±20%)為主。

　　The accuracy and material type of capacitor should be selected reasonably. If the accuracy of the commercial chip capacitor is less than 0.01 μ F, the accuracy can reach class J (± 5%); if the accuracy is above 0.01 μ F, the accuracy of J class is less, and K class (± 10%) is the majority; if the accuracy is above 0.1 μ f, the accuracy is mainly of class m (± 20%).

　　(4)市場上尺寸代碼為0805片狀電容器的容量規(guī)格（系列）最齊全，而0603一些的容量可能會缺貨。在生產批量不太大時，為防止市場缺貨而影響生產，可以將焊盤稍作延伸，使它能適用于0603及0805，避免造成因缺件而停產。

　　The capacity specifications (Series) of chip capacitors with size code 0805 are the most complete on the market, while some capacities of 0603 may be out of stock. When the production batch is not too large, in order to prevent the market shortage from affecting the production, the pad can be extended slightly to make it suitable for 0603 and 0805, so as to avoid production stop due to lack of parts.

　　(5)片狀多層陶瓷電容器都是卷裝的，型號在帶盤上，而電容器上無任何標志。雖然可以用測量方法知道其容量，但很難區(qū)別材料類別的精度等級。因此在使用過程中，特別是手工裝配時務必小心。

　　The multi-layer ceramic capacitors are all packaged in coils, and the model is on the reel, but there is no mark on the capacitor. Although its capacity can be known by measurement, it is difficult to distinguish the accuracy level of material category. Therefore, in the process of use, especially manual assembly must be careful.

　　(6)敞開式片狀微調電容器不能用波峰焊，而封閉式片狀微調電容器可用波峰焊。

　　Wave soldering can't be used for open chip trimming capacitor, but wave soldering can be used for closed chip trimming capacitor.

　　(7)片狀電容器普遍采用多層結構，在使用時有些人采用烙鐵手工焊接，此時一定要注意焊接速度，避免過熱，造成基化端頭因溫差大而斷裂，使容量下降。

　　The multi-layer structure is widely used in sheet capacitors. Some people use soldering iron for manual welding. At this time, attention must be paid to the welding speed to avoid overheating, resulting in the breakage of the base end due to large temperature difference, resulting in the reduction of capacity.
