in a psu a general yes but the peek load with go up on the diodes before it you could go for a 47uF and the peek load with go down but you might get some hum.. if it is the start up cct from a switch mode and the thing starts with a 100uF or a 47uF then fine.. you can get 68uF 50V caps from some suppliers. and in any case the tolerances on these caps is + or - 20% ish anyway.. hope this helps..
Simple answer,,,Yes, you can.

∙ 9y agoNo, because the 1000uF 10V capacitor rating means that it will reach 1000uF capacitance at 10 volts, while the 1000uF 25V capacitor will reach the same capacitance at 25 volts.
The above statement will only matter if your electronic circuit is very specific/sensitive towards capacitance.

∙ 6y agoCapacitors in this range of values are usually electrolytic. You should be able to get away with it but don't go any higher in voltage rating or the capacitor will degrade: gradually losing capacitance and developing excessive leakage current which can cause it to overheat.
You should never replace a capacitor with one having a lower voltage rating than the original, but for electrolytics you should alway stay as close to the original rating as you possibly can to maintain reliable operation and safety factors.

∙ 11y agoThere's certainly nothing that prevents you from making the replacement, but you
might not like the result. If the circuit was designed for a 1000uf of capacitance at
that point, then it won't operate as designed with a different value there. For example,
in the power supply of a high-power audio amplifier, a small background hum might
appear, and the harmonic distortion at peak volume levels would certainly increase.

∙ 13y agoThe voltage written on the capacitor indicates the highest voltage it is rated for. If you are putting the 25v capacitor in a circuit that will not run over 25v, then yes.
Wiki User
∙ 11y agoIn general, yes. The exception is if the capacitor is used in a tuned circuit. Then you need to use the correct capacitance. Increasing the voltage is not an issue.

∙ 10y agoIt's ok except in a few circuits which use the capacitor to control the frequency response of the circuit. In power supplies or for general decoupling it would be perfectly ok.

Yes, the same capacity is the key. If you replace it with a higher voltage it will still perform normally. If the voltage is less than the original it may explode.

Can you replace a 470uf 10v capacitor with a 470 25v 105c high temp radial leads capacitor for a digital tv converter box?
Yes, as long as there is room to mount the larger capacitor. A better replacement might be a 470uF 16v capacitor, which should be smaller than the 25v cap. If necessary, insulating tubing can be put on the leads & the cap can be mounted off the board, or at an angle to the board. Remember to observe polarity when connecting the capacitor leads to the board. Note the orientation & markings on the old capacitor before unsoldering it.
Can you replace 2200 uf 24 volt capacitor with a 2200 uf 16 volt capacitor?
NO dont do it if you devalue a capacitors voltage parameter what will it do when it is face to face with 20V ? The voltage will destroy the thing. Remember it is OK for you to use a higher voltage parameter for a capacitor but never lower
Can a capacitor in a lcd television be changed if cant find exact numbers eg 220 25v instead of 220 16v and what would change be?
Yes, the higher voltage is not only OK, but is desirable, as it will be longer-lasting. It is very important to replace the capacitor with the same type. If it is a ceramic disk, replace it with a ceramic disc. If it is metal-film, then replace it with a metal-film capacitor, and so on.
What is the difference between a 47uf 50 v capacitor and a 47uf 25v capacitor for a tattoo machine?
A: It may tattoo your face when it blow up if the 25 volts is used where a 50 volts should be, you may substitute 47 mfd 500 volts for the 50volts cap and the 25 volts cap But you cannot substitute 15 volts for the 25 volts capacitor
Can you replace a 25v 500uf capacitor with 25v 470uf capacitor?
It will depend on the application. If you are trying to rapair some thing which as per design needs 470uF capacitor but you only have 100uF capacitors available., you can put 5 of these in parallel if possible (if SMD you can put one on top of another and solder). That will give you a total of 500uF close to the original value. - Neeraj Sharma
Can you replace a 40v light bulb with a 25v one?
No, it is not recommended to replace a 40v light bulb with a 25v one. The voltage rating of the bulb should match with the voltage of the electrical circuit to ensure proper operation and prevent damage. Using a bulb with a lower voltage rating can cause it to burn out quickly or potentially create a safety hazard.
What is the factor of 25v plus 19v plus 4?
That's 44v + 4 which factors to 4(11v + 1)
How work ic 7805 and his constrction?
1. connect pin #1 to source (input voltage), pin #3 to the load (output), pin #2 to ground. 2. at the input 100 uF electrolytic capacitor, at least 25V (the higher capacitance is better, its to make sure that the source will provide the energy for prompt consumption from the 7805 regulator 3 At the ouput connect 0.1uF ceramic capacitor (for noise filtering) and in parallel anoher high capacitance (at least 10uF) electrolytic capaciotr ( 6.3V or higher) also in order to provide the energy for prompt consumption from the load
Is it a step up or a step down a transformer has 20 primary windings and 100 secondary windings the secondary voltage is 25v?
If a transformer has 20 primary windings and 100 secondary windings, it is a step up transformer. If the secondary voltage is 25v, the primary voltage will be 5v, because the turns ratio is 20 to 100, or 1 to 5.
Why rs232 voltage level converting to ttl level?
RS-232 is a standard built a longer while ago, and its specifications dictate a maximum voltage of +-25V. HIGH signal levels at +-5V, +-12V and +-15V are not uncommon. The range of operation is from -25V to +25V. Also, RS-232 standard notes that levels between -3V and +3V are illegal (as in, they are assumed not to exist, nor carry any information). On the other hand, TTL stands for Transistor-Transistor Logic, and the maximum rating for that is 5V. HIGH signal levels are at any point above 3.5V. The range of operation is between 0V and 5V. If one were to connect these with no conversion, the TTL device would probably be burned. Even if it would withstand, the designs are sufficiently different for them not to communicate properly. Thus, the need to 'bridge the gap' between the two.

A dc motor running on a potential difference of 25V draws 9.8A It lifts a load of 48lb 12ft?
A dc motor running on a potential difference of 25 volts draws 9.8 A. It lifts a load of 48 pounds 12 feet in 5.5 seconds. How much work does the motor do? How much power does it deliver? How much poser does it consume? What is its efficiency?
