Inductance coil is a device that uses the principle of electromagnetic induction to work. When a current flows through a wire, a certain electromagnetic field will be generated around the wire, and the wire of this electromagnetic field will induce the wire within the range of this electromagnetic field. The effect on the wire itself that generates the electromagnetic field is called "self-inductance", that is, the changing current generated by the wire itself produces a changing magnetic field, which further affects the current in the wire; the effect on other wires in the electromagnetic field range, Called "mutual inductance".

The electrical characteristics of inductance coils are opposite to capacitors, "passing low frequencies and blocking high frequencies". When high-frequency signals pass through the inductance coil, they will encounter great resistance and it is difficult to pass; while the resistance presented by low-frequency signals passing through it is relatively small, that is, low-frequency signals can pass through it easily. The resistance of the inductor to direct current is almost zero.

Resistance, capacitance and inductance, they all present a certain resistance to the flow of electrical signals in the circuit. This resistance is called "impedance". The impedance presented by the inductor to the current signal uses the self-inductance of the coil. Inductance coil is sometimes referred to as "inductance" or "coil", represented by the letter "L". When winding an inductance coil, the number of turns of the coil is generally called the "number of turns" of the coil.

There are roughly the following categories of inductance coils commonly used in circuits:

Classified according to the form of inductance: fixed inductance, variable inductance.

Classified according to the nature of the magnetic conductor: air core coil, ferrite coil, iron core coil, copper core coil.

Classified according to the nature of work: antenna coil, oscillating coil, choke coil, trap coil, deflection coil.

Classified according to winding structure: single-layer coil, multi-layer coil, honeycomb coil, close-wound coil, inter-winding coil, out-of-body coil, honeycomb coil, random-winding coil.

The Inductor Coil Manufacturer Briefly Describes the Performance Indicators of the Inductor Coil for You

The inductance of an inductor coil is a key performance index, determined by factors such as the number of turns, winding method, and presence of a magnetic core. The basic unit of inductance is Henry (H), with common units including millihenry (mH) and microhenry (μH). Inductance coils also exhibit inductive reactance and a quality factor (Q) related to their efficiency. Distributed capacitance and rated current are also important considerations.

Inductor coil manufacturers tell you the role of inductance coils

Choke effect: The self-induced electromotive force in the inductance coil always counteracts the current change in the coil. The inductance coil has an obstructive effect on the alternating current, and the size of the obstructive effect is called the inductive reactance xl, and the unit is ohm. Its relationship with inductance l and alternating current frequency f is xl=2πfl, and inductors can be mainly divided into high-frequency choke coils and low-frequency choke coils. Tuning and frequency selection: The inductance coil and the capacitor are connected in parallel to form an lc tuning circuit. That is, the natural oscillation frequency f0 of the circuit is equal to the frequency f of the non-AC signal, and the inductance and capacitive reactance of the loop are also equal, so the electromagnetic energy oscillates back and forth between the inductance and the capacitance, which is the resonance phenomenon of the lc loop. At resonance, the inductive reactance and capacitive reactance of the circuit are reversed. The inductive reactance of the total loop current is the smallest and the current is the largest (referring to the AC signal of f="f0"). The lc resonance circuit has the function of selecting the frequency and can An AC signal of frequency f is selected.

A Brief Introduction to the Principle of Use of Inductance Coils

Inductance is the ratio of magnetic flux to current in a wire with AC. When AC passes through a coil, the magnetic field lines change over time, generating an induced electric potential, equivalent to a new power source. This prevents current changes in AC circuits, similar to inertia in mechanics. Inductance is related to coil turns, size, shape, and medium, and measures the inertia of the inductor.

Why use magnetic beads and inductors?

Reasons for using magnetic beads and inductors 1. The choice of magnetic beads or inductors mainly depends on the application. 2. Inductance is needed in the resonant circuit; when eliminating unwanted EMI noise, using magnetic beads is the best choice. 3. Applications of magnetic beads and inductors: Inductors: radio frequency (RF) and wireless communications, information technology equipment, radar detectors, automotive electronics, cellular phones, pagers, audio equipment, PDAs (personal digital assistants), wireless remote control systems, and Low-voltage power supply modules, etc. 4. Magnetic beads: clock generating circuit, filtering between analog circuit and digital circuit, I/O input/output internal connectors (such as serial port, parallel port, keyboard, mouse, long-distance telecommunications, local area network), radio frequency (RF) circuit Between the logic devices that are susceptible to interference, the power supply circuit filters out high-frequency conduction interference, and suppresses EMI noise in computers, printers, video recorders (VCRS), TV systems and mobile phones.
