Can you use a different voltage capacitor?
You can’t really go wrong choosing a higher voltage-rated capacitor than the voltage that the power supply will supply it, but you can definitely go wrong choosing a lower voltage-rated capacitor than the voltage that it will be exposed to. So don’t expose a capacitor to a higher voltage than its voltage rating.
Can I use a lower microfarad capacitor?
It might not work, it might damage something else, but you ‘can. ‘ Replacing with a slightly higher uF should be fine however. A capacitor that is lower in MFD by 10\%, will function ok. 20\% undersize may reduce starting torque.
Can I replace capacitor with higher voltage?
Originally Answered: Can I replace a certain value capacitor with the same value but higher voltage? In a nutshell, yes you can. For basic hobbyist electronics or repairing a power supply, you can safely replace the cap with a higher V rating but not much higher.
Can I replace a capacitor with a lower capacitance?
Yes, it’s safe. The only rating that matters for safety is the rated voltage: if you put a higher voltage than the maximum you might see your cap explode.
Can I use a 35v capacitor instead of an 50V?
Yes, you can replace a 35v capacitor with a 50v or 63v or with any voltage rating that meets or exceeds the original. The only caveat is to make sure that the replacement capacitor will physically fit where the old cap was. Higher voltage rated caps are usually larger in size. There shouldn’t be a problem.
Can I use higher microfarad capacitor?
There is a maximum of +10\% tolerance in microfarad rating on replacement start capacitors, but exact run capacitors must be replaced. Voltage rating must always be the same or greater than original capacitor whether it is a start or run capacitor.
Can you replace capacitor with lower UF?
The rule of thumb is to select capacitors with voltage ratings higher than those expected in the circuit as a buffer. So, if you decide to replace a capacitor with a lower uf one, make sure that the new capacitor has the same voltage rating of the one you are replacing or is larger.
Can I use 35V capacitor instead of 25V?
If you compare the above parameters, going from 25V to 35V won’t cause a problem. The majority of low ESR parts are 25V or lower, so you’ll find less and less high-performance capacitors once you get above 35V. There is a maximum rating.
Can I replace capacitor with higher UF?
An electric motor start capacitors can be replaced with a micro-farad or UF equal to or up to 20\% higher UF than the original capacitor serving the motor.
