The Shielded Inductor wholesaler and shielded Inductor Service provider share daily tips and tips on the shielded inductor, power inductor, wire wound inductor and other shielded inductors.
The one-piece chip inductor is a shielded inductor. The one-piece chip inductor is mainly composed of two parts - the magnetic core and the wire group. Its production is to embed the enameled wire into the magnetic core powder and use the machine to die-cast it. The pins are on the face of the inductor.
The integrated chip inductor has a more stable structure, lower impedance and better seismic performance. At the same time, because of its structure, it can largely avoid noise generation and reduce electromagnetic interference.
1. Small size and thin structure, suitable for surface mount fully automated production, high production efficiency;
2. Strong solderability and high temperature resistance;
3. Made of metal powder die-casting, low loss, low impedance, leadless pins, small parasitic capacitance;
4. The material of the magnetic core is very particular, the workmanship is very fine, and the working frequency covers a wide range.
Such as complex workmanship, high production technology requirements, high-end production equipment, and relatively high production costs.
There are many products in our daily life that need to use converters for operation, such as DC-DC converters used in our mobile phones, digital cameras, audio and video media players and other products. The function of the DC-DC converter is that the DC-DC converter can perform high-frequency switching actions through a controllable switch (MOSFET, etc.), and store the input electrical energy in the inductor. When the switch is turned off, the electrical energy is released to the load. provide energy. However, inductive components are used in DC-DC converters—one-piece chip inductors. Do you know which scenarios should one-piece chip inductors be used in addition to DC-DC converters?
The function of the integrated chip inductor on the DC converter is mainly to filter, and the current of the integrated chip inductor is still relatively large. Chip inductors are also used in tablet computers and notebook computers. In addition, integrated chip inductors are also used in chargers and power supplies.
In addition, in the field of DC/DC converters of voltage regulation modules: integrated chip inductors are often used in the field of voltage regulation and DC/DC converters, which can improve product performance, save circuit board space and reduce energy consumption.
In the field of portable mobile devices such as mobile phones: integrated chip inductors are suitable for high-temperature commercial products, including the latest generation of mobile devices, notebook computers, desktop computers, servers, computer graphics cards, portable game consoles, car navigation, and high-current power supplies.
Application of multiple integrated chip inductors on high-speed PC graphics cards: integrated chip inductors are often widely used in high-speed PC graphics cards/CGA modules, differential mode filter inductors, communication networks, automotive electronics and other fields
The integrated chip inductor can be used independently when it is used, it will not affect its performance characteristics, and it does not need to be used in conjunction with other products.
In the world of electronics, inductors play a crucial role in shaping circuits' functionality. These passive components are essential for energy storage, filtering, and signal processing. Among the various types of inductors, wire-wound inductors stand out due to their unique construction and performance characteristics.
Read on to learn about inductors, including what a wire wound inductor is, how it works, its types, applications, advantages, and disadvantages.
An inductor is a passive electronic component that stores energy in a magnetic field when electric current flows through it, a property known as inductance, measured in Henries (H). Inductance arises from the magnetic field generated around a conductor, which induces voltage-opposing changes in current, making inductors valuable for signal smoothing and noise filtering.
Inductors are crucial in various applications, including power supplies, which filter high-frequency noise to smooth out voltage, and RF (Radio Frequency) circuits, which tune and match impedance. These are also essential in transformers for energy transfer between circuits and energy storage systems to maintain a steady power supply.
A wire wound inductor consists of a coil of wire, typically made of copper or aluminum due to its excellent conductivity, wound around a core. The core can be made from air, iron, or ferrite, each imparting different inductive properties.
The construction of wire wound inductors involves different winding techniques, including single-layer, multilayer, and toroidal winding, each offering distinct performance characteristics.
Wire wound inductors are known for higher inductance values and greater current handling capabilities than other inductor types, such as multilayer and film inductors. While multilayer inductors consist of multiple layers of conductive material separated by insulating layers and film inductors, they use thin films of conductive material. Wire wound inductors excel in applications demanding high inductance and reliability due to their superior performance and strength.
To understand the functionality of a wire wound inductor, it is essential to explore how it generates a magnetic field, the role of the core material, and the impact of wire turns and spacing on its inductance.
When an electric current flows through the coil of a wire wound inductor, it generates a magnetic field around the coil. The strength of this magnetic field depends on the current flowing through the coil and the number of turns of wire.
Role of Core Material
The core material plays a crucial role in enhancing the inductance of a wire wound inductor. Core materials like air, iron, and ferrite have varying magnetic properties.
Air cores are used for high-frequency applications, iron cores for high inductance values, and ferrite cores to balance high inductance and frequency stability.
Impact of Wire Turns and Spacing

The number of wire turns and the spacing between them significantly impact the inductance value. More turns and tighter spacing result in higher inductance.
The winding technique also affects the inductor's performance, with precision winding techniques offering better control over inductance values.
Wire wound inductors come in different types based on the core material used. Each type offers unique characteristics suited for specific applications:
Air Core Inductors
Air-core inductors lack a core material and utilize an air-filled space for winding. They excel in high-frequency applications requiring low inductance values and offer stability without core losses.
Iron Core Inductors
Iron-core inductors utilize iron cores to enhance inductance, which is ideal for applications needing higher inductance values, such as power supplies. While iron cores boost permeability, they may introduce losses at higher frequencies.
Ferrite Core Inductors
Ferrite-core inductors use ceramic ferrite cores, offering high inductance and stability across frequencies. Due to their balanced properties, they are versatile for RF circuits, filters, and energy storage applications.
Wire wound inductors are versatile components used in various electronic devices and systems:
Power Supplies
In power supply circuits, wire-wound inductors help smooth out the output voltage by filtering out high-frequency noise.
Radio Frequency (RF) Circuits
RF circuits utilize wire wound inductors for tuning and impedance matching, ensuring efficient signal transmission and reception.
Filters and Chokes
Inductors are integral to the design of filters and chokes, which block or attenuate unwanted frequencies in a circuit.
Transformers and Energy Storage
Wire wound inductors are also used in transformers for energy transfer between circuits and energy storage applications, where they help maintain a steady power supply.
Wire wound inductors offer distinct advantages and disadvantages that impact their suitability for various electronic applications.
High Inductance Values: They can achieve significantly higher inductance values than other inductors, making them ideal for applications requiring substantial energy storage.
Stability: These inductors maintain stable inductance across frequencies and temperatures, ensuring consistent performance in diverse operating conditions.
