An electrical device with conductive plates separated by an insulating material called a dielectric.
Common types:
electolytic capacitors are polarized. Be careful!
To determine the value of a capacitor:
The multiplier stands for how many zeros to add to the first two values.
The result is the capacitance value in picofarads (pF).
For capacitors less than 100pF, only a two digit number is printed on the capacitor, or a two-digit number followed by a "0". A 55pF capacitor may be marked as 55 or 550.
To use this table, just read across. For example, 1uF is same 1,000nF or 1,000,000pF.
Common types:
- mica
- ceramic
- plastic film
- electolytic
electolytic capacitors are polarized. Be careful!
Function
Essentially, a temporary battery, capable of storing up an electrical charge.Operating Values
There are two ratings:- A voltage rating, which specifies the maximum voltage that can be applied without damaging the component.
- A capacitance value, which is rated in farads and is typically printed on the capacitor itself
