Can I use a 50V capacitor instead of an 35v?
Yes. Just don’t go below 25v. The 4.7uF is an “exact” value, whereas the 25v is a maximum rating. Probably yes: Ideally you should replace the capacitor with one of the same nominal capacitance and an equal or greater maximum voltage rating.
What does uF stand for on capacitor?
micro farad
uF refers to the size of the capacitor. Capacitance is the charge that is necessary to raise the potential of a body one unit. A capacitance of 1 farad (f) requires 1 coulomb of electricity to raise its potential 1 volt (v). 1 micro farad (uF) = 0.0000001 F. Dannie Musser.
What are the replacement rules for capacitors?
REPLACEMENT RULES FOR CAPACITORS. The microfarad (strength) rating of a replacement start capacitor must be equal to or no greater than 20% of the original start capacitor. 4. If capacitors are wired in parallel the total capacitance (microfarad rating) is equal to the sum of the individual capacitors.
Can a capacitor be used with the same voltage?
Use a capacitor with the same capacitance, and the same or higher voltage rating. Also, Q is charge, and although it is the product of voltage and capacitance, you must use the applied voltage, not the rated. There’s more to it than just capacitance and Vmax rating.
Can you substitute a 35V capacitor for a 470uf?
I have a ton of random junk that has various capacitors with other specs. For example, one is labeled 35v 470uf. So, suppose I want to substitute this 35v capacitor.
What’s the best way to reform an electrolytic capacitor?
This method uses a large series resistor and a high-voltage power supply to reform capacitors that are NOS (new-old stock) or capacitors removed from the equipment’s chassis. Voltage-Limited Method 1: The voltage-limited methods use a handy device called the variable autotransformer (a.k.a. Variac, General Radio’s brand name).
