Inductors are passive two-terminal electrical components that store energy in a magnetic field when electricity flows through it. Inductors are made up of 7 different segments all delivering against the same objective of storing and then releasing energy. These segments include; Coupled, Mulitlayer, Moulded, Power, High Frequency (RF), Surface Mount and Air Core.
These inductors share a magnetic path and influence each other, making them handy for stepping up or stepping down voltage.
This type of inductor provides greater inductance, but only at lower maximum operating frequencies.
These inductors are housed within a plastic or ceramic housing and can be encapsulated to provide improved environmental protection from heat, cold and moisture.
While this inductor can handle higher levels of power, it also generates more noise that requires magnetic shielding.
High-frequency or radio frequency inductors are designed to operate at higher frequencies, but require additional design and manufacturing techniques to reduce losses.
These inductors are often very small and geared towards use in tight applications like mobile devices.
These inductors not use a magnetic core made of a ferromagnetic material. The coils are wound on plastic, ceramic, or other nonmagnetic forms, as well as those that actually have air inside the windings.
