      電解電容應用極為廣泛,凡是涉及到電子類的產品中都會用到電解電容,其中用于家用電器和各種電子產品最具有代表性,其容量范圍較大,一般為1~33000μF,額定工作電壓范圍為6.3~700V。

      Electrolytic capacitors are widely used. Electrolytic capacitors are used in all electronic products. They are most representative for household appliances and various electronic products. Their capacity ranges from 1 to 33000 μ F. The rated working voltage range is 6.3~700V.

    三和電解電容

      電解電容的缺點是介質損耗、容量誤差較大(最大允許偏差為+100%、-20%),耐高溫性較差,存放時間長容易失效。

      The disadvantages of electrolytic capacitors are large dielectric loss and capacity error (the maximum allowable deviation is+100%, - 20%), poor high temperature resistance, and easy failure due to long storage time.

      電解電容的極性,注意觀察在電解電容的側面有“-”是負極、“+”是正極,如果電解電容上沒有標明正負極,也可以根據它的引腳的長短來判斷,長腳為正極,短腳為負極。

      The polarity of the electrolytic capacitor shall be observed that "-" is the negative pole and "+" is the positive pole on the side of the electrolytic capacitor. If the electrolytic capacitor is not marked with positive and negative poles, it can also be judged according to the length of its pin. The long pin is the positive pole and the short pin is the negative pole.

      有極性電解電容器通常在電源電路或中頻、低頻電路中起電源濾波、退耦、信號耦合及時間常數設定、隔直流等作用。

      Polarized electrolytic capacitors usually play the role of power filter, decoupling, signal coupling, time constant setting and DC isolation in power circuit or medium frequency and low frequency circuit.

      一般不能用于交流電源電路,在直流電源電路中作濾波電容使用時,其陽極(正極)應與電源電壓的正極端相連接,陰極(負極)與電源電壓的負極端相連接,不能接反,否則會損壞電容器。

      Generally, it cannot be used in AC power supply circuit. When it is used as filter capacitor in DC power supply circuit, its anode (positive pole) should be connected with the positive end of the power supply voltage, and its cathode (negative pole) should be connected with the negative end of the power supply voltage, which cannot be reversed, otherwise the capacitor will be damaged.

      無極性電解電容器通常用于音箱分頻器電路、電視機S校正電路及單相電動機的起動電路。

      The non-polar electrolytic capacitor is usually used in the loudspeaker divider circuit, the television S correction circuit and the starting circuit of single-phase motor.

      電解電容主要應用于車載行業、安防行業、 醫療電子、電腦電視、電子玩具、工業控制、LED驅動電源、智能家電。電解電容的選型也很重要,工程師要根據電容的工作環境、溫度、體積、壽命等多重因素來選擇適合的型號。如有需求可隨時與我們取得聯系。

      Electrolytic capacitors are mainly used in vehicle industry, security industry, medical electronics, computer television, electronic toys, industrial control, LED drive power supply, and smart home appliances。The selection of electrolytic capacitor is also very important. The engineer should select the appropriate model according to the working environment, temperature, volume, life and other factors of the capacitor. If you need, please feel free to contact us.
