How to match capacitors to make it work best
Our products revolutionize energy storage solutions for base stations, ensuring unparalleled reliability and efficiency in network operations.
Another solution, if you cannot find an exact duplicate, is to combine two capacitors together. Two capacitors in parallel will add (a 20μF in parallel to a 30 μF would make a 50 μF capacitor). Two capacitors in series will end up being the inverse of the sum of the inverses of their capacitances (two 100 μF in series would make a 50 μF).
