Axial Leaded Inductor RWW4*15-6uH High Precision and Voltage Choke Coil Filter ​

1.Product Description

RWW4*15-6uH axial leaded inductor is a common electronic component widely used in various electronic circuits. It consists of a coil, a magnetic core (some may be coreless), and axial leaded pins. The term “Axial Leaded” refers to the fact that the pins protrude axially from both ends of the inductor body. This structure facilitates plug-in installation on printed circuit boards (PCBs) by inserting the pins into the corresponding holes on the PCB and soldering them in place to realize the connection to the circuit.

The bobbin of the I-inductor is made of the winding bracket of the copper core coil. Inductance is one of the attributes of an electronic circuit or device, referring to: when the current changes, due to electromagnetic induction and resistance to current change of the electromotive force some large fixed I-inductors or adjustable inductors (such as oscillating coils, choke coils, etc.), commonly used I-inductors are regarded as the vertical version of axial inductance, convenient application and axial inductance similar, However, commonly used inductors can have a larger volume of inductor types, and the current can naturally be improved to a certain extent; Most of them are enameled wire (or gauze wire) directly wrapped around the skeleton, and then the magnetic core or copper core, iron core, etc. is loaded into the inner cavity of the skeleton to improve its inductance. The skeleton is usually made of plastic, bakelite, ceramic, and can be made into different shapes according to actual needs. Small inductors (such as I-inductors) generally do not use a skeleton, but directly wrap the enamelled wire around the magnetic core.

2.Function

--Energy Storage: RWW4*15-6uH Axial Leaded Inductor has the characteristic of storing magnetic field energy. When the current passes through the axial lead inductor, it will be converted into magnetic field energy stored; when the current changes, the stored magnetic field energy will be converted into electrical energy released, so as to maintain the relative stability of the current in the circuit.

--Filtering: In power supply circuits and signal processing circuits, RWW4*15-6uH Axial Leaded Inductor is often used in conjunction with capacitors and other components to form filters. It can prevent high-frequency signals through, while allowing low-frequency signals or DC component through, thus filtering out the circuit of the clutter and interference signals, improve the stability of the power supply and signal quality. For example, at the output of a switching power supply, an LC filter circuit composed of an inductor and a capacitor can effectively reduce the ripple in the output voltage and provide a smooth and stable DC-power supply.

--Choke: In some circuits, RWW4*15-6uH Axial Leaded Inductor can play the role of choking, i.e., limiting the change of current. For example, in AC circuits, the inductor presents a certain impedance (inductive resistance) to the AC current, the size of which is proportional to the inductance value and the frequency of the AC current. By choosing the inductance value appropriately, the magnitude of the AC current can be limited to prevent damage to circuit components caused by excessive current.

--Oscillation: In the oscillation circuit, RWW4*15-6uH Axial leaded Inductor and capacitor form an LC oscillation loop, which can generate a specific frequency oscillation signal. This oscillating signal has a wide range of applications in radio communications, clock circuits and other fields, providing a stable frequency source for the circuit.
