Help capacitor selection of some common sense

All electronic components, the capacitor type, model, specification and features, the most complicated, especially for the demand of the differences between the circuit and working environment, even if is the same with rated voltage capacitance, also can have different kinds and material characteristics of capacitance selection. In electrolytic capacitor, for example, because of its capacity is large, although can and plastic film capacitors or ceramic capacitor area lies between each other, actually use differences still has the following features: (1) temperature range of use: selected ordinary goods - 25 ℃ to + 85 ℃ or high temperature resistant products 40 ℃ to + 105 ℃. (2) the height of capacitance choice: the same specifications of capacitance general variety of height and width of the corresponding, mainly to make a distinction between shrinkage body quality and ordinary quality; Without the use of highly restricted, choose ordinary goods. (3) the capacitance tolerance range: in the absence of indicating, general capacity range is + / - 20%, plus or minus 10%, other -- 10% ~ + 30%, 0 ~ + 20%, etc. ; In general the capacity of ordinary product - to set in the specified value About 10%. (4) low leakage current: for some particular circuit, related to the charge and discharge time constant accuracy. (5) low ESR: for some filter circuit, need to cooperate with the filtering effect of high frequency pulse high current, such as the filter circuit of switching power supply. 6 non-polarity: used for low frequency high reflection amplitude of the audio signal pathway, to avoid both ends of the capacitor is reverse bias, output waveform distortion.
