Profile
- These electronic parts control the flow of electricity.
- They’re one of the three musketeers of electronic parts you need to make a circuit. The three musketeers are capacitors, inductors, and resistors.
- Inductors also go by the name “coils” sometimes.Coils are twisty shapes. Inductors are often made with coiled wires, so they are sometimes called “coils”.
The Power of Inductors
Inductors have infinite uses.
Inductors make a force called “magnetism” when electricity flows through them. Magnetism can do things like change or stabilize the way electricity flows.
They also make batteries last longer in smartphones and video game systems. Inductors can do all kinds of things, so they are in all sorts of machines.
The Secret of the Power of Inductors
Inductors like to argue!
As the flow of electricity gets stronger, inductors make it harder for the flow to get any stronger than it has to. When the electricity gets weaker, inductors push back against that, too.
Without an inductor, electricity goes straight through if the flow of electricity increases. Inductors help machines run smoothly by arguing with the electricity.
Friends of Inductors
Wire-wound Type Inductors
An inductor with a coiled wire.
Multilayer Type Inductors
A stack of printed sheets without a wire coil. These can be smaller than wire-wound types.
Film Type Inductors
Made with layers of thin film.
Trivia
What are the symbol and unit for inductors?
Inductor performance is measured in units of H (henry). Inductors with different H values have different uses.
What are they used for?
We use inductors to get Wi-Fi™ and other connections to reach far away!
