Electrical SMRH105 Shielded Power Inductor Smd Choke Coil Power
Inductor 22UH
Product performance:
The power inductance also has an air-core coil and a magnetic core. The main feature is to use Thick wire wound, can withstand tens of amps, hundreds, thousands, or even tens of thousands of amps.
Power chip inductors are divided into two types: with magnetic cover and without magnetic cover, mainly composed of magnetic core and copper wire. It mainly plays the role of filtering and oscillation in the circuit.
Feature:
1. The flat bottom surface is suitable for surface mount.
2. Excellent end face strength and good solderability.
3. It has the characteristics of high Q value and low impedance.
4. The characteristics of low leakage flux, low direct resistance
and high current resistance.
5. Tape packaging can be provided to facilitate automated assembly
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.
