How we choose a capacitor---Recommendations for choosing a capacitor

     Radio amateurs use aluminum, tantalum,Ceramic capacitors and many others. From the correct choice of the capacitor depends its reliability during operation, as it should be used in such modes of operation that do not exceed the specified conditions. For this purpose, it is necessary to determine the values ​​of the nominal parameters and their permissible changes during operation, possible modes and electrical loads, design, reliability and durability indicators, mounting options, dimensions and mass.
     Practice shows that the permitted The voltage indicated on its housing should not be less than in the electrical circuit. You can choose more by 20-30%. Capacity can be used within + -10%, but it is better to take it no less than the electrical circuit. 
    If the capacitors must be in a circuit Power, shunting the high frequency (high frequency), then it is better to use ceramic. If they should be installed in the frequency-setting stage, then it is better to take them with a small TKE (temperature coefficient of capacitance), so that there is no frequency drift. In all cases, capacitors should be used for lower loads and light modes (compared to the maximum permissible ones).
