AI Customer ServiceA ceramic capacitor can be selected as an input capacitor. When using a ceramic capacitor, attention must generally be paid to temperature changes and to changes in capacitance due to the DC bias.
AI Customer ServiceThe first objective in selecting input capacitors is to reduce the ripple voltage amplitude seen at the input of the module. This reduces the rms ripple current to a level which can be handled by bulk capacitors. Ceramic capacitors placed right at the input of the regulator reduce ripple voltage amplitude.
In essence, the input capacitor is selected on the basis of these parameters, but in trial manufacture and evaluation, checks must be performed to ensure that the input voltage with ripples added do not exceed the withstand voltage, and that heat generation caused by the ripple current can be tolerated.
・Important issues in capacitor selection include the rated voltage, rated ripple current, characteristic for heat generation by ripples, and when using a ceramic capacitor, the temperature characteristic and DC bias characteristic in particular. ・Input capacitors must be able to tolerate higher voltages and currents than output capacitors.
Depending on what you are trying to accomplish, the amount and type of capacitance can vary. The first objective in selecting input capacitors is to reduce the ripple voltage amplitude seen at the input of the module. This reduces the rms ripple current to a level which can be handled by bulk capacitors.
The following three parameters are important when selecting the input capacitor. 1） Rated voltage 2） Rated ripple current and ripple heat generation characteristics 3） When using a ceramic capacitor: temperature characteristic and DC bias characteristic Moreover, the following should be born in mind as premises for selection.
Among the different types of capacitors, the multilayer ceramic capacitor (MLCC) is particularly good regarding allowable ripple current. A starting point is to select the key ceramic capacitors to meet the requirements for ripple voltage and current. Table 1 shows five different ceramic capacitors that were chosen for this article.
