SMRH127 Shielded Smd Power Inductor PCB Coil Inductor
Product performance:
The inductance in the electronic circuit is an air-core coil, or a
coil with a magnetic core, which can only pass a small current and
withstand a lower voltage; and 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.
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.
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.
The resistor is used to control the current in the circuit, the capacitor is used to block DC and AC, and the inductor is used to block high frequency and low frequency. Chip inductors have the characteristics of preventing the passage of alternating current and allowing direct current to pass smoothly in the circuit. The characteristics of the inductor are to pass DC and block AC. The higher the frequency, the greater the coil impedance. Inductors often work with capacitors in circuits
Inductor coils have the property of preventing current changes in AC circuits. The inductance coil has similar characteristics to the inertia in mechanics, and is named "self-induction" electrically. When the chip inductor is at low frequency, the inductance generally exhibits inductance characteristics, which only store energy and filter high frequency characteristics, but At high frequencies, its impedance characteristics are obvious. There are phenomena such as energy consumption and heating, and the reduction of perceptual effects. Different inductors have different high frequency characteristics.
