Can the magnetic ring inductor be interchanged with the I-shaped inductor?
Release Date:2022-09-17
Both the magnetic loop inductor and the I-shaped inductor are used to control the circuit signal. When the inductance value is the same, can the magnetic loop inductor and the I-shaped inductor be interchanged to a certain extent? First, let's take a look at their respective characteristics:
H-shaped inductor has the characteristics of high power, high magnetic saturation, low impedance and small size. The I-shaped inductor is not only small in size, but also easy to install. It is a plug-in type inductor and takes up less space; High Q factor; The distributed capacitance is small; High self resonance frequency; The special guide pin structure is not easy to produce closed-circuit phenomenon. I-shaped inductors use wires to pass AC voltage and current. I-shaped inductors generate alternating magnetic flux around the inside of the wire when the wire passes AC current. The ratio of the magnetic flux of the wire to the current producing the magnetic flux. I-shaped inductors are generally used for circuit matching and signal quality control, and generally for connection and power supply connection.
Magnetic loop inductor is a common anti-interference component in electronic circuits, which has a good weakening effect on high-frequency noise. It is generally made of ferrite materials. The magnetic ring has different impedance characteristics at different frequencies. Generally, the impedance is very small at low frequencies. When the signal frequency increases, the impedance of the magnetic ring increases sharply. As we all know, the higher the signal frequency, the easier it is to radiate, and the general signal lines have no shielding layer, so these signal lines will become a good antenna to receive all kinds of messy high-frequency signals in the surrounding environment, and these signals will be superimposed on the originally transmitted signals, or even change the originally transmitted useful signals. Under the action of the magnetic ring, normal and useful signals can pass through well, and high-frequency interference signals can be reduced.
To sum up: under the condition of the same inductance value, it mainly depends on what role they play in the circuit. If they are just filtering, they are all for signals and can be replaced each other naturally; If it is an oscillating circuit, the magnetic ring inductance and the I-shaped inductance can be exchanged, but the I-shaped inductance is more durable than the magnetic ring.
