三和samwha电解电容是针对不同行业研发定制的不同系列的电解电容产品，如rd系列、wf系列、wl系列等等都是使用较为广泛的系列，且品质高，口碑好。
samwha electrolytic capacitors are different series of electrolytic capacitor products developed and customized for different industries, such as rd series, wf series, wl series, etc. they are widely used series with high quality and good reputation.
电容的类型有很多种，电解电容、贴片电容、超级电容、钽电容、薄膜电容等，但电容的本质原理是一样的，都是同交流阻直流，存储电荷和开释电荷。
there are many types of capacitors, such as electrolytic capacitor, chip capacitor, super capacitor, tantalum capacitor, film capacitor, etc., but the essential principle of capacitor is the same, which is the same as ac resistance dc, storage charge and release charge.
1、一般电解电容的电容偏差大些，不会严重影响电路的正常工作，所以可以取电容量略大一些或略小一些电容器代替。但在分频电路、s校正电路、振荡回路及延时回路中不行，电容量应和计算要求的尽量一致。在一些滤波网络中，贴片电容与电解电容的容量也要求非常准确，其误差应小于±0.3%～0.5%.
generally, the capacitance deviation of electrolytic capacitors is larger, which will not seriously affect the normal operation of the circuit, so capacitors with slightly larger or smaller capacitance can be used instead. but not in frequency division circuit, s correction circuit, oscillation circuit and delay circuit. the capacitance shall be consistent with the calculation requirements as much as possible. in some filter networks, the capacitance of chip capacitor and electrolytic capacitor is also required to be very accurate, and the error should be less than ± 0.3% ~ 0.5%
2、耐压必须达到要求，选用的耐压值应等于或大于原来的值。
the withstand voltage must meet the requirements, and the selected withstand voltage value shall be equal to or greater than the original value.
3、无极性电容通常选用无极性电容来替换，实在无办法到时可用两只容量大一倍的有极性电容逆串联后代替，方法是将两只有极性贴片电容与电解电容的正极相连或将它们的两个负极相连。
the non-polar capacitor is usually replaced by the non-polar capacitor. there is no way to replace it by reverse series connection of two polar capacitors with twice the capacity. the method is to connect the two polar patch capacitors with the positive pole of the electrolytic capacitor or their two negative poles.
4、在选用贴片电容与电解电容时，建议选择三和samwha耐高温系列电容产品，耐高温电容的最高工作温度为105℃，当其在最高工作温度条件下工作时，能保证2000小时左右的正常工作时间。工作环境的温度越低，电容的使用寿命越长。
when selecting chip capacitor and electrolytic capacitor, it is recommended to select samwha high temperature resistant series capacitor products. the maximum working temperature of high temperature resistant capacitor is 105 ℃. when it works at the maximum working temperature, it can ensure the normal working time of about 2000 hours. the lower the temperature of the working environment, the longer the service life of the capacitor.
