Capacitor Marking
A capacitor marking is a code, which indicates the value of the component. It usually consists of three numbers, which indicates the value, and a letter, which indicates the tolerance. Tables usually provide a means to decode the numbers; however, there are also calculators available as well. It is easy to decode because the first two numerals ...

Capacitor Polarity: What You Need to Know
Arrow: Some polarized capacitors have an arrow marking on the negative terminal to indicate the direction of the current flow. It is important to note that non-polarized capacitors do not have polarity markings, as they can be connected in any direction without any issues. Verifying the polarity markings on the capacitor and connecting the positive terminal to the higher voltage …

Capacitor Colour Codes
The capacitor on the left is of a ceramic disc type capacitor that has the code 473J printed onto its body. Then the 4 = 1 st digit, the 7 = 2 nd digit, the 3 is the multiplier in pico-Farads, pF and the letter J is the tolerance and this translates to: 47pF * 1,000 (3 zero''s) = 47,000 pF, 47nF or 0.047uF the J indicates a tolerance of +/- 5%. Then by just using numbers and letters as codes ...

Capacitors (A-level electricity in physics)
Capacitors. A capacitor also known as a condenser, is a device which is used to store electric charge. A capacitor consists of two metal plates separated by an insulator called dielectric usually air or oil. A dielectric is a nonconductor of electric charge in which an applied electric field causes a displacement of charge but not flow of charge.
