Inductors, coils, and transformers are all types of electrical components that are used to store or convert electrical energy. Inductors are passive devices that use electromagnetic induction to store energy in the form of a magnetic field. Coils are simply inductors that have been wound into a spiral shape, and they are often used in the same applications as inductors.
Transformers are electrical devices that use electromagnetic induction to convert electrical energy from one voltage level to another. They are typically used to step up or step down the voltage of an electrical signal, and they are commonly used in power distribution systems and other applications.
Accessories for inductors and transformers can include a wide range of items, such as mounting hardware, connectors, and termination caps. These accessories are used to assist in the installation and use of these components.
