Maybe you have some old power supplies you can scavenge old used caps from, anything would be better than GP capacitors. If you use a 25v rated cap, never Jan 16, 2013 · For future reference keep in mind if you did need an odd capacitance and were using parts with a low enough tolerance to make sense (some types can be closer to 1%) then you can place standard values in parallel to get a close match. 3v For Power Boards with main boards marked VA4 837-9538, you need the same capacitors as the list above and an additional C9 10uF 16v Step 8 — Audio Board Capacitors Mar 18, 2022 · Sometimes someone will just put them all together in one spot on the schematic instead of showing them in a way that reflects their physical locations. The only downsides to using a higher value or higher voltage capacitor is physical size and cost. The voltage rating is the naximun that the cap can handle. This makes me think that its possible to use a different one. Louis P New member. 3 - In DC realm, both a battery and a capacitor will discharge what is required to satisfy Ohms law. The difference between 40+5 F and 45+5 F capacitors is not much worth saying. If you use a 25v rated cap, never exceed 25V. Note that you should provide capacitor Y0 for suppression of switching noise from the regulator. Replace ONE 25v 47uf capacitor with FIVE 60v 10uf capacitors parallel? 2. The voltage rating is the maximum voltage you can deal with. 25V would do just fine, 16V should work as well but it's a bit low. Can be replaced with 16 or 25v rated capacitor as well, and you can probably also go up in capacitance to 1500uF without any risks. The main thing you need to know about capacitors is that they store X charge at X voltage; meaning, they hold a certain size charge (1µF, 100µF, 1000µF, etc. You can't use just any kind of capacitor, for example you shouldn't use a capacitor removed from an old radio or an old CRT TV, which aren't subjected to the same high frequencies and currents as in monitor power supplies. 3V cap instead, and the same goes for the 5V rail. And for the 12V rail, you always need at least a 16V cap. We can use capacitors for many purposes: Control timing —for example, used with IC timer 555 to control charging and discharging; Smoothing —for example, in the power supply; Coupling —-for example, connecting the audio system and speakers; Filtering — for example, in the bass-treble tuning circuit of the audio system Dec 19, 2023 · Capacitors are important for storing electrical energy.

Aug 4, 2013 · If you use a cap that is say 100V in a circuit that is only using 15V then you may over time find that the capacitor will not perform to its rated capacity because the dielectric has changed. Apr 29, 2017 · Aluminum electrolytics are available in low impedance versions now, and high capacitance ceramic caps have become more available (though they tend to shrink greatly in capacitance when biased- for most high capacitance types- so a 10uF ceramic cap might be 3 or 4uF when you put full voltage across it). Probably yes: Ideally you should replace the capacitor with one of the same nominal capacitance and an equal or greater maximum voltage rating. Slow Learner. So in my opinion, it is perfectly safe to use a 25V cap for a 15V DC line. 3V. When connecting a battery to a discharged capacitor, the current drawn can be extremely high as the cap charged up. Is this a safe replacement? I believe you are fine with increasing the voltage rating, but I am not sure about the capacitance rating. So, using it won’t change the performance of the circuit. Never exceed 25V when using a 25v rated cap. But the latter comes with a slight risk of overheating. Can I use these instead or source 2200uf ones? Last edited: Monday at 2:46 AM.

If the capacitor has a rated cap of 16 volts, you can never exceed that voltage. The only caveat is to make sure that the replacement capacitor will physically fit where the old cap was. Sometimes it is also safe to use capacitors with a larger capacitance (Farads). A capacitor’s voltage rating indicates the highest voltage that may be applied to it without damaging it. Meaning, I will use a 25V cap on a 12. Jul 26, 2014 · The choice of dielectric involves a trade between how much capacitance we need in a given area, how much capacitance drift we can tolerate vs. Stack Exchange network consists of 183 Q&A communities including Stack Overflow, the largest, most trusted online Jan 31, 2021 · But you first need to match the voltage, the originals are 25v and your new one is 16v.

It's 6% Most large-ish capacitors have very wide tolerances in the first place, and circuits which use them are very rarely sensitive. And, a higher (uF) value won't hurt anything. It can be harmful to operate a capacitor close to or above its voltage rating. I've also have found capacitors of 470 uF/16 V, just in case this information be important. Can I replace a capacitor with a lower uF? Can you replace a start capacitor with a lower uF? – Quora. A good question. You may be sure that the 63V capacitor will operate within its acceptable voltage range as long as the ratio V_applied / V_rating_63V is lower than the ratio V_applied / V_rating_25V. The second number is the voltage rating, which indicates the maximum voltage to which the capacitor can be exposed. The voltage rating of a capacitor is the maximum only, they will work fine at any voltage less than I desoldered the caps from the board, and I need a 470 microfarad, 25v capacitor, but I can only find 470uf 35v capacitors at the shack. . Feb 26, 2022 · This first number indicates the amount of energy the capacitor can handle at a certain voltage. Ideally, you should replace the capacitors with one that has the same nominal capacitance and maximum voltage rating. For example, a capacitor has a voltage rating of 25V, so the capacitor can work properly and safely without any damage up to the maximum voltage of 25V. Being a newb, I figured that would get me started in my project. putting a 2200uF 25V or 35V one in as a replacement wont hurt. liberally seasoned with opinion came one alleged kernal of wisdom from a NICHICON DESIGN ENGINEER.
