What does the Voltage Rating on a Capacitor Mean?
Take note that a capacitor''s voltage rating is not the voltage that the capacitor will charge up to, but only the maximum amount of voltage that a capacitor should be exposed to and can store safely. For the capacitor to charge up to the desired voltage, the circuit designer must design the circuit specificially for the capacitor to charge up to that voltage.
Capacitor Types [Use Cases + How to Choose the Right One]
Capacitors typically have markings that indicate their capacitance value (often in microfarads, µF), voltage rating, and sometimes the type (e.g., ceramic, …
Basic Electronics – Selecting a Capacitor, Capacitor Values
The capacitor''s voltage rating should always be at least 1.5 times or twice the maximum voltage it may encounter in the circuit. Capacitors are not as reliable as resistors. They get easily damaged once the applied voltage nears …

Decoupling Capacitor Calculations: What Size Should You Use …
Looking for a decoupling capacitor calculator or how to calculate decoupling capacitor value? Bypassing and decoupling are two terms that are thrown around willy-nilly. Here''s how the correct decoupling capacitor size will ensure power and signal integrity in your
voltage regulator
I am using a voltage regulator, and to get cleaner power, the datasheet recommends using a 0.33uF capacitor. However, it doesn''t say what type it wants. Stupidly, I went out and bought a 10 pack of 0.33uF 50V Radial Electrolytic Capacitors.After looking up on this site, I found that the symbol means that it is a unpolarized capitator. ...
How To Select a Capacitor
While you might know what capacitance or voltage rating your project requires, capacitors have lots of other characteristics — such as polarization, …

How to pick voltage rating for capacitors
In a 100nF cap the dielectric will be much thicker than in a 1µF plate, so if both are the same size, the 100nF cap will show less voltage dependence. TL/DR: for 3V3 it doesn''t really matter unless the …
How to Choose PCB Capacitor
This means that, if your expected drop in voltage across your pcb capacitor is 10Volts, then you should choose a capacitor having a 15 volts rated voltage or more. Lifetime expectancy or the capacitor life can be defined …
How to Select the Right Aluminum Electrolytic Capacitor
Capacitor voltage ratings provide a safe operating range for a capacitor. Operating within these ratings prevents them from being damaged and extends their functional life. Aluminum electrolytic capacitors most commonly provide bulk capacitance to power supply voltage rails.
