Are there any important differences in how the capacitors behave if one is physically larger by a significant amount? A big factor that affects size/volume (if the capacitance is held constant) is the voltage rating. So, if both capacitors (small and large) have the same capacitance then one will (more than likely) work up to a larger voltage.
Similarly PP capacitors tend to be somewhat better and larger than polyester (Mylar). There are newer SMT-compatible (high temperature) film dielectrics such as PPS that are middling good. That''s just an overview of a
Generally speaking, the bigger the capacitor the darker the tone, and the smaller the capacitor the brighter the tone. A capacitor''s value, or capacitance, can give you an idea of just how it will affect tone, from slightly warm all the way to dark. Here are some guidelines: A Quick Reference for Capacitor Values Capacitance (in UNITS)
1. The large-capacity capacitor can make the voltage stable and can withstand the instantaneous output of a large current. The power amplifier circuit will not be distorted
Polyester capacitors, on the other hand, offer better tolerance, higher voltage ratings, and are more suitable for applications requiring larger capacitance values and linear performance. It''s important to consider these
Why does the much larger more powerful amp have 2/3''s the capacitance rating? The Parasound amp is about a decade newer than the larger vintage amp, so did capacitor
What I noticed also is that the bigger the capacitor size, the longer it took for the voltage to stabilise. Meaning that, for the 100 uF cap, it took approximately 40 ms for the voltage to rise and stay fixed at 4.1 V, unlike with
Some say that a slightly higher value (eg 10000 uF instead of 8200 uF) offers better bass. Do not exceed, however, it is always advisable because you could have problems
I''ve observed through experience that the voltage rating of an electrolytic capacitor has more effect on its size than its capacitance. For example, I have a 1000μF 10V
A capacitor tries to hold its voltage, and the bigger the capacitor, the better it does. The rate of change of voltage on the capacitor is equal to the current into or out of it, divided by the capacitance. So here''s what happens in that circuit. I''ll start with the PUT off (not conducting current) and the capacitor discharged.
Using a bigger cap is not always the best answer. Ideally, the capacitor should be sized for the amount of charge needed to supply transient current to the circuit for which the capacitor is filtering or decoupling.

The power amplifier circuit will not be distorted when it is instantaneously high dynamic output. 2. The larger the capacitance, the more the AC interference can be filtered out, so the sound quality is more
Smaller capacitors increase the perimeter/area ratio. Additionaly the fringing capacitances from the top terminal to the substrate, considering you want to create a floating capacitor (none of the terminals connected to GND), increase compared to the case of a

Capacitance, voltage, ripple current, and temperature should all be considered while choosing a capacitor. The fluctuation in each of these factors affects the physical size of the capacitance, and the size variation differs for each type of
The larger the capacitance of the capacitor, the lower the resonance frequency, and the smaller the frequency range in which the capacitor can effectively compensate for the current. Therefore, in order to ensure the
I''ve observed through experience that the voltage rating of an electrolytic capacitor has more effect on its size than its capacitance. For example, I have a 1000μF 10V capacitor which is less than half the size of a 470μF 35V capacitor that I have.
The last but not the least to think about is the physical dimension as well as the mounting style. Sometimes capacitor selection is dictated by the space available. Chip capacitors has small footprints but with limited capacitance value. On the other hand, electrolytic capacitors have bigger capacitance, but they are bulky. Are you going to use
Smaller capacitors increase the perimeter/area ratio. Additionaly the fringing capacitances from the top terminal to the substrate, considering you want to create a floating
On average, the cost of capacitor replacement typically ranges from $100 to $300, including both the cost of the capacitor itself and the labor for installation. However, this is a general estimate, and actual costs may vary based on individual circumstances.
Capacitance, voltage, ripple current, and temperature should all be considered while choosing a capacitor. The fluctuation in each of these factors affects the physical size of the capacitance, and the size variation differs for each type of capacitor, including paper capacitors, mica capacitors, ceramic capacitors, and electrolytic capacitors.
The larger the capacitance of the capacitor, the lower the resonance frequency, and the smaller the frequency range in which the capacitor can effectively compensate for the current. Therefore, in order to ensure the ability of the capacitor to provide high-frequency current, the larger the capacitor, the better.
The main downside of a bigger capacitor is that the switch on rise time and switch off fall time will be greater. That means more stress on the regulator during startup and
This is where the problem lies. All capacitors are not equal in their performance. Using a bigger cap is not always the best answer. Ideally, the capacitor should be sized for the amount of charge needed to supply transient current to the circuit for which the capacitor is filtering or decoupling. Therefore, it is important to know your
The main downside of a bigger capacitor is that the switch on rise time and switch off fall time will be greater. That means more stress on the regulator during startup and in extreme cases may even cause an overcurrent shutdown of the regulator. It can also cause problems for loads which don''t handle undervoltage very well.
Additionally, using higher voltage capacitors often indicates a higher tolerance for ripple currents and better performance in terms of capacitance drift, enabling the circuit to deliver more stable and reliable operation over time. However, there are also substantial considerations and potential drawbacks that need to be carefully evaluated

For precise applications, a lower-tolerance capacitor should be chosen since a higher-tolerance capacitor is not appropriate. There are capacitors available with the same capacitance but varying amounts of tolerance. The capacitance value determines the physical size of the capacitor; as the capacitance rises, the size expands.
Larger caps have the tendency to respond well to DC-type signals whereas smaller value chip caps have a much higher frequency response (see Figure 1). The key is to know your environment and use a combination of smaller capacitors in parallel with the larger capacitors if possible — especially in your board development.
The main downside of a bigger capacitor is that the switch on rise time and switch off fall time will be greater. That means more stress on the regulator during startup and in extreme cases may even cause an overcurrent shutdown of the regulator. It can also cause problems for loads which don't handle undervoltage very well.
Capacitors are derated by selecting one that is two to three times greater than the expected operating voltage. This increases the footprint requirements and physical size of the capacitor. In practical applications, ripple current or leakage current flows through the dielectric, and the ripple current rating must be considered.
The larger the capacitance of the capacitor, the lower the resonance frequency, and the smaller the frequency range in which the capacitor can effectively compensate for the current. Therefore, in order to ensure the ability of the capacitor to provide high-frequency current, the larger the capacitor, the better.
