Rules for replacing capacitors
Webb14 mars 2024 · Always use a voltage rating significantly higher than the circuit voltage, such as at least 35V or more, for use with a 25V supply. Better parts do cost more, so they are mostly used when needed, not routinely. Some sensitive circuits will need low leakage capacitors, or parts with better drift and accuracy.

Webb8 juni 2024 · Almost any capacitor with matching capacitance (4700 uF) and matching or exceeding the other parameters is fine. So the voltage must be at least 25V, but it can be … Webb19 aug. 2024 · Like batteries, capacitors also have an expected useful life and will require replacing. As the materials within capacitors age and degrade, they lose the ability to effectively perform their job. The electrolyte, paper and aluminum foil inside the capacitor degrades physically and chemically.
Webb21 jan. 2024 · Replacing these caps is fairly easy, although can be quite a time consuming depending on both the quantity and location of each capacitor inside the chassis. Fortunately, it’s not a job that must be done regularly with most needing replacement every 10 years or so, depending on usage. Webb19 aug. 2024 · Like batteries, capacitors also have an expected useful life and will require replacing. As the materials within capacitors age and degrade, they lose the ability to …
WebbUse 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.

WebbProbably yes: Ideally you should replace the capacitor with one of the same nominal capacitance and an equal or greater maximum voltage rating. Unless otherwise marked, for electrolytic capacitors (likely the type you are using) the tolerance of the capacitance is usually -20% to +80% of the nominal rating.
Webb3 mars 2012 · So yes, recapping justifies full attention in old (20 years +) amplifiers or even any newer, hot running electronics for that matter.
