A choke core, also known as an inductor core, is a type of electrical core used in inductors and other types of electrical equipment. Inductors are devices that store energy in a magnetic field and are used in a wide range of applications including power supplies, electronic filters, and transformers.
Choke cores are typically made from a material that has a high magnetic permeability, such as iron or ferrite. This high permeability allows the core to store more magnetic energy than a core made from a material with a lower permeability. This is important in applications where high inductance is required.
There are several different types of choke cores available, each with their own unique characteristics. The most common types include powdered iron cores, ferrite cores, and laminated cores. Powdered iron cores are made from small particles of iron that are pressed and sintered together. Ferrite cores are made from a ceramic material that contains iron oxide. Laminated cores are made from thin sheets of iron or steel that are stacked together and held in place with a binding material.
Powdered iron cores are known for their high permeability and low cost, making them a popular choice for low-power applications. Ferrite cores are known for their high impedance, making them a good choice for high-frequency applications. Laminated cores are known for their high inductance and high core loss, making them a good choice for applications that require high inductance and high-power handling capabilities.
Choke cores can be used in a wide range of applications, including power supplies, electronic filters, and transformers. They are also commonly used in the automotive and aerospace industry, as well as in consumer electronics such as televisions, computers and mobile phones.
