三和电解电容

  电解电容的缺点是介质损耗、容量误差较大(最大允许偏差为 100%、-20%),耐高温性较差,存放时间长容易失效。

  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.

  电解电容的极性,注意观察在电解电容的侧面有“-”是负极、“ ”是正极,如果电解电容上没有标明正负极,也可以根据它的引脚的长短来判断,长脚为正极,短脚为负极。

  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.

  有极性电解电容器通常在电源电路或中频、低频电路中起电源滤波、退耦、信号耦合及时间常数设定、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.

  一般不能用于交流电源电路,在直流电源电路中作滤波电容使用时,其阳极(正极)应与电源电压的正极端相连接,阴极(负极)与电源电压的负极端相连接,不能接反,否则会损坏电容器。

  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.

  无极性电解电容器通常用于音箱分频器电路、电视机s校正电路及单相电动机的起动电路。

  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.

  电解电容主要应用于车载行业、安防行业、 医疗电子、电脑电视、电子玩具、工业控制、led驱动电源、智能家电。电解电容的选型也很重要,工程师要根据电容的工作环境、温度、体积、寿命等多重因素来选择适合的型号。如有需求可随时与我们取得联系。

  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.
