            三和samwha電解電容是針對不同行業研發定制的不同系列的電解電容產品,如RD系列、WF系列、WL系列等等都是使用較為廣泛的系列,且品質高,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.

          三和電解電容

            電容的類型有很多種,電解電容、貼片電容、超級電容、鉭電容、薄膜電容等,但電容的本質原理是一樣的,都是同交流阻直流,存儲電荷和開釋電荷。

            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、一般電解電容的電容偏差大些,不會嚴重影響電路的正常工作,所以可以取電容量略大一些或略小一些電容器代替。但在分頻電路、S校正電路、振蕩回路及延時回路中不行,電容量應和計算要求的盡量一致。在一些濾波網絡中,貼片電容與電解電容的容量也要求非常準確,其誤差應小于±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、耐壓必須達到要求,選用的耐壓值應等于或大于原來的值。

            The withstand voltage must meet the requirements, and the selected withstand voltage value shall be equal to or greater than the original value.

            3、無極性電容通常選用無極性電容來替換,實在無辦法到時可用兩只容量大一倍的有極性電容逆串聯后代替,方法是將兩只有極性貼片電容與電解電容的正極相連或將它們的兩個負極相連。

            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、在選用貼片電容與電解電容時,建議選擇三和samwha耐高溫系列電容產品,耐高溫電容的最高工作溫度為105℃,當其在最高工作溫度條件下工作時,能保證2000小時左右的正常工作時間。工作環境的溫度越低,電容的使用壽命越長。

            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.
