Basically, the value of a schematic component calls out its most important characteristic.Ĭomponent names are usually a combination of one or two letters and a number. Crystals might list their oscillating frequency as their value. For other components, like integrated circuits, the value may just be the name of the chip. For schematic components like resistors, capacitors, and inductors the value tells us how many ohms, farads, or henries they have. Values help define exactly what a component is. The component symbols tell half the story, but each symbol should be paired with both a name and value to complete it.
