In electronics, a choke is an inductor used to block higher-frequency alternating currents (AC) while passing direct current (DC) and lower-frequency ACs in a circuit. A choke usually consists of a coil of insulated wire often wound on a magnetic core, although some consist of a doughnut-shaped ferrite bead strung on a wire.

Excellent for power line DC/DC conversion applications used in hard disk, notebook computers and other electronic equipment. Excellent solderability and high heat resistance. Excellent terminal strength construction. Packed in embossed carrier tape and can be used by automatic mounting machine.

2023年10月26日 · Filter chokes, also known as inductor chokes or simply chokes, are essential components in electronic circuits that serve to block high-frequency alternating current (AC) while allowing direct current (DC) to pass through.

Understanding the difference between chokes and inductors is essential when designing devices and machinery that rely on electrical power. These electrical components each suit specific applications. Chokes. A choke is a type of inductor, but its application, function, and design differ from other inductor designs. Typically, this electrical ...

A power choke inductor is an inductive coil of wire that stores energy in a magnetic field when current flows through it. It has an ability to prevent the flow of high-frequency signals while allowing the flow of low-frequency signals.

A choke is an electrical component that is designed to block or reduce the flow of high-frequency signals while allowing low-frequency signals to pass through. Chokes are commonly used in electronic circuits to filter out noise, reduce electromagnetic interference, and provide stable power supplies. There are different types of chokes available ...
