You can simulate the effect of a non-polar capacitor with polar capacitors and diodes, if you connect them correctly. simulate this circuit – Schematic created using CircuitLab As an AC voltage is applied across this combination, each diode will rectify, and charge up the centre node.
Quick question: Replace a capacitor for one with a little much higher capacitance?
Hi, I''m working on fixing a circuit right now and I need a quick answer if possible: can I replace a 2.2mf capacitor with a 10mf capacitor? Voltage is not a problem here.
Ceramic vs. Film Capacitor: Which one is preferred in audio circuits?
However, as I was reading the circuit schematic, I noticed that the author denotes that the capacitors C101, C104, and C105 are supposed to be "film capacitors." Is there a reason as to why one would use film instead of ceramic capacitors in this application
Can I replace all electrolytic capacitors with ceramic?
Since applied voltage can change the dimensions of the capacitor, changing its dimensions by applying stress can change its open-circuit voltage. In effect, the capacitor acts as a microphone. It can pick up the mechanical vibrations the board is subjected to, and those can make their way into the electrical signals on the board.
