jb Knowledge of Capacitors

1. How many main types of the capacitor?
There are mainly four types of capacitor, I.E. Film capacitor, Aluminum electrolytic capacitor, ceramic capacitor & tantalum capacitor.
jb capacitors mainly produce the first two types, MKT MKP film capacitors & aluminum electrolytic capacitors. visit www.jbcapacitors.com for more details.
2. Do you know capacitors markings mean?

Most capacitors have numbers printed on their bodies to indicate their electrical characteristics. Large capacitors like electrolytic capacitors usually display the actual capacitance together with the unit, for example, "220uF". Smaller capacitors like ceramics, however, use a shorthand consisting of three numbers and a letter, where the numbers show the capacitance in pF (calculated as XY × 10Z for the numbers XYZ) and the letter indicates the tolerance (J, K or M for ±5%, ±10% and ±20% respectively).  For Example:
A capacitor with the text 473K 330V on its body has a capacitance of 47 × 103 pF = 47 nF (±10%) with a working voltage of 330 V.

3. What is capacitors' Construct?

capacitor is composed of two conductors separated by an insulating material called a DIELECTRIC. The dielectric can be paper, plastic film, ceramic, air or a vacuum. The plates can be aluminum discs, aluminium foil or a thin film of metal applied to opposite sides of a solid dielectric. The CONDUCTOR - DIELECTRIC - CONDUCTOR sandwich can be rolled into a cylinder or left flat
