Electrical SMRH125 Shielded Power Inductor Smd Choke Coil Power
Inductor 22UH
Attributes:
Chip inductance is a property of a closed loop. When the coil of the chip inductor passes current, the chip inductor forms a magnetic field induction in the coil, and the induced magnetic field will generate an induced current to resist the current passing through the coil. The role of the chip inductor in the circuit is to generate a changing magnetic field when an unsteady current is passed, and this magnetic field will in turn affect the current. , It is high resistance to high frequency pulses, so it plays the role of passing DC resistance AC pulses.
Application:
Products are widely used in digital products, PDAs, notebook computers, mobile phones, network communications, graphics cards, LCD backlights, power modules, automotive electronics, security products, office automation, home appliances, walkie-talkies, electronic toys, sports equipment and medical equipment, etc.
Structure and composition:
Chip inductors are a commonly used electronic component. When the current passes through the wire, a certain electromagnetic field will be generated around the wire, and the wire in this electromagnetic field will generate an induced electromotive force-self-induced electromotive force, which we call electromagnetic induction. In order to enhance electromagnetic induction, people often wind the insulated wire into a coil with a certain number of turns.
