What is a 1000 uF capacitor?
Typically these are used for surge suppressing / transient voltages / filtering out noise at the ~1KHz or less. This specific capacitor is rated for 1000uF and 25V with a +/- 20% tolerance. The negative is denoted by a white line down the side of the capacitor with a negative symbol.
What is meant by 1000 micro F?
The microfarad (symbolized µF) is a unit of capacitance, equivalent to 0.000001 (10 to the -6th power) farad. In RF scenarios, capacitances range from about 1 pF to 1,000 pF in tuned circuits, and from about 0.001 µF to 0.1 µF for blocking and bypassing.
Can I use 25V capacitor instead of 50v?
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 a 10uF capacitor do?
Since the cap (short in the electronic world for capacitors) is rated for 10uF, it can hold a charge of ten micro coulombs (that is, ten millionths of a Coulomb, 0.000010 C) per volt of voltage across its terminals. It tells you how much voltage a capacitor can handle across its terminals before it goes KABOOM………!
What is the rate of capacitor?

What is the basic unit of a capacitor?
The capacitance of a capacitor is a measure of its ability to store charge, and the basic unit of capacitance is the Farad , named after Michael Faraday. The Farad is defined: A capacitor has a capacitance of one Farad when a potential difference of one volt will charge it with one coulomb of electricity (i.e. one Amp for one second).
What is farad in capacitor?
Named for scientist Michael Faraday of England, the farad is a unit of electrical capacitance. If a device called a capacitor stores a charge of 1 coulomb at a potential difference of 1 volt across its plates, it is a one-farad capacitor.
What is the value of 1 farad?
The farad measures how much electric charge is accumulated on the capacitor. 1 farad is the capacitance of a capacitor that has charge of 1 coulomb when applied voltage drop of 1 volt. 1F = 1C / 1V Table of capacitance values in Farad
What is the meaning of UF on a capacitor?
Technically ‘mfd’ represents ‘milliFarad’ while ‘uF’ stands for ‘microFarad’ which is an order of magnitude smaller. Here is where the confusion begins. Some older capacitor manufacturers used ‘mF’ in place of uF on their capacitors.
