6 FAQs about [Based on what value to choose capacitor]

How do I choose a capacitor value?

You choose a capacitor value by using the RC time constant: This constant gives you the time it takes for a voltage in an RC circuit to go from 0% to 63% of its full value. You can use this time constant to calculate the cutoff frequency in a filter, or just how long a delay will be in a blinking light circuit.

What is a standard capacitor value?

Like 0.47 µF or 22 pF. It is a bit confusing, but it’s easy to learn what it means. In this article you will learn the most standard capacitor values, the prefixes used and how to calculate a capacitor value for your circuit. Capacitor values are given in Farad. The symbol used is F. It’s named after the English physicist Michael Faraday.

What factors should be considered when choosing a capacitor?

Apart from the suitability of different capacitors for specific applications, other important factors that may need to consider include the following: Tolerance – It must be checked if the working of the circuit depends on precision capacitance. A capacitor with the lowest tolerance should be used if it requires narrow capacitance.

Where are capacitor values given?

Capacitor values are given in Farad. The symbol used is F. It’s named after the English physicist Michael Faraday. But 1 Farad is pretty big. So capacitor values are usually given with a prefix. Often you are going to work with capacitors values in pico-farads to micro-farads.

What is a good voltage rating for a capacitor?

The capacitor physical size is directly proportional to the voltage rating in most cases. For instance, in the sample circuit above, the maximum level of the voltage across the capacitor is the peak level of the 120Vrms that is around 170V (1.41 X 120V). So, the capacitor voltage rating should be 226.67V (170/0.75).

What type of capacitor should I use?

Unless there are specific circuit requirements, and if the required capacitance is in Picofarad, a ceramic capacitor can be used. If the required capacitance is in Nanofarad, MLC (Multilayer Ceramic) capacitors can be blindly trusted. If the capacitance necessary is in Microfarad, aluminum electrolyte capacitors are a common choice.
