New Energy Sources WhatsAppYes, you can use 5x 100uF capacitors in parallel to get 500uF capacitance. It is like 1x 500uF capacitor. But there is some advantage. Capacitors with lower capacity usually have lower ESR. So when you use 5 smaller caps instead of 1 bigger one you will get better performance in this respect. This is common practice.

New Energy Sources WhatsAppA filter capacitor is a capacitor which filters out a certain frequency or range of frequencies from a circuit. Usually capacitors filter out very low frequency signals. These are signals that are very close to 0Hz in frequency value.
New Energy Sources WhatsAppReplacing a capacitor with something that has a higher voltage rating is always safe. The only problem there is that a capacitor rated for a higher voltage is often physically larger, everything else being equal. Make sure they actually fit in the same space. Sometimes it is also safe to use capacitors with a larger capacitance (Farads).

New Energy Sources WhatsAppFilter Capacitor- Explained. A filter capacitor is a capacitor which filters out a certain frequency or range of frequencies from a circuit. Usually capacitors filter out very low frequency signals. These are signals that are very close to 0Hz in frequency value. These are also referred to as DC signals. How Filter Capacitors Work
New Energy Sources WhatsAppESR is no longer the single dominant factor in output filter ripple and noise voltage, now ESL also becomes a limiting parameter for output filter capacitors. Total output filter inductance should be 1 nH or less for many high frequency SMPS designs. This forces designers to consider surface mount (SM) components to eliminate inductance.
New Energy Sources WhatsAppHow large should we make the filter capacitor? From the spec sheet, we learn that the dropout voltage of the LM7805 is 2.5V. Therefore, the valley of the peak-to-peak ripple should be 9V + 2.5V = 11.5V. Assuming that the average rectified DC voltage is 12VDC, the minimum negative peak of the ripple voltage = 12V – 11.5V = 0.5V.

New Energy Sources WhatsAppUsually filters are designed so that the resistance and capacitance values are chosen in such a way that you don''t need to go to capacitors that are made with Class 2 or Class 3 materials that exhibit the DC bias effect and can simply use capacitors with Class 1 materials which do not exhibit the DC bias effect.
New Energy Sources WhatsAppThe short answer is that high-capacity capacitors are not good for filtering high-frequency noises. It''s common to use the small ones to filter out high-frequency noises. It is all because the capacitors are not ideal. An ideal big capacitor must filter any noise bigger than the cut-off frequency of the circuit.
