Is there any downside to using a larger than needed smoothing capacitor?
I work with low-power DC voltage regulators. I am already aware of the formula to calculate the size of smoothing capacitor(s). This can be an iterative process of testing one size with a scope and $begingroup$ This reason may be buried in one of the many good answers Some (only) regulators can be damaged by the output capacitor …

What makes capacitors special is their ability to store energy; they''re like a fully charged electric battery. Caps, as we usually refer to them, have all sorts of critical applications in circuits. Common applications include local …
Can You Use a Larger Run Capacitor?
A Larger Run Capacitor Will Allow You to Run More off of a Single Power Supply. Here''s How to Tell if You Can Use a Larger Capacitor. Run Capacitors A run capacitor is an electrolytic capacitor with a relatively high capacitance value. A run capacitor is used to store electrical energy and to help maintain a constant voltage level.
8.2: Capacitance and Capacitors
Figure 8.2.5 : A variable capacitor. For large capacitors, the capacitance value and voltage rating are usually printed directly on the case. Some capacitors use "MFD" which stands for "microfarads". While a capacitor color code exists, rather like the resistor color
How to Discharge a Capacitor
If your capacitor is rated for a voltage higher than 600V, you need a larger multimeter to make appropriate measurements. Place Multimeter Probes on Capacitor Terminals What you do in this second step depends on whether your capacitor has polarity.

How to Discharge a Capacitor Safely: A Comprehensive Guide
Personal Injury: In extreme cases, the discharge of a large capacitor can cause severe burns, muscle contractions, or even cardiac arrest if the electrical current passes through the body. Fire Hazard: Capacitors store …
How to Make a Capacitor
A capacitor is a device for storing a small electric charge. When two conductive plates are separated by a small insulator called a dielectric, they produce an electric field. The strength of this field is called the …
How to Safely Discharge Capacitors
Large AC capacitors can store charges that can injure and even kill you by stopping your heart. They should be treated with extreme care. Is It Safe to Discharge a Capacitor With an Insulated …
HVAC Start and Run Capacitor Explained and Replacement – …
A Start Capacitor holds a charge to start a motor moving. A Run Capacitor keeps a motor running smoothly with no big up and down spikes. A Start capacitor helps a motor start to turn, while a Run capacitor helps …
How to Safely Discharge a Capacitor
Capacitors are electronic components found in almost every device containing a circuit board. Large capacitors can store enough charge to cause injuries, so they must be discharged properly. While iFixit currently doesn''t sell a capacitor discharge tool, you can easily create your own.
Make a SUPER HIGH VOLTAGE Capacitor
Need a high voltage capacitor? Then look no further! You could make a Leyden Jar, but why not something with 10 times more capacity and smaller?It would be p...
Capacitor types
Large capacitors tend to have higher ESL than small ones because the distances to the plate are longer and every mm counts as an inductance. For any discrete capacitor, there is a frequency above DC at which it ceases to behave as a pure capacitor. This ...
How to make electrolytic capacitors at home
Here''s how I made an electrolytic capacitor starting with a simple low capacity one (stores a small amount of energy) and then moving on to a higher capacity one (stores more energy). 60 microfarad simple …
