In a project, an electrolytic capacitor for 3 V. is ordered. In my stock one of 50 V. Can I use it without any problems?
In fact, it is recommended that the replacement capacitor has a voltage equal to or greater than the original. However, this larger one is relative. What perhaps many do not know is that the capacitance of an electrolytic also depends on the working voltage. A capacitor from 1 uF to 50 V, for example, will have a lower capacitance when operating at 3 V. So, for a slightly larger voltage range, for example, up to about 12 V. the capacitance difference will be small and it can be used. Electrolytic capacitors usually have large tolerances.
