Types of Inductor in Electronics

A custom inductor is a crucial component in electronic circuits, working by storing energy in a magnetic field within its coil. When the current changes, the magnetic field's change induces a voltage in the coil. As a trustworthy custom inductor manufacturer, we provide custom inductors that play a vital role in applications like filtering, signal processing, and energy storage, making them an indispensable part of modern electronic devices. Our inductor factory excels in designing and producing high-quality custom inductors tailored to meet specific requirements, ensuring optimal performance and reliability.

Specific Information for Custom Inductor

  • Principle of Operation: Custom inductors work on the principle of inductance, which is a property that opposes changes in electric current passing through it, due to the magnetic field generated by the current.

  • Types and Applications: There are various types of custom inductors provided by custom inductor manufacturers such as air core, iron core, and ferrite core, each with unique characteristics. They are widely used in power supplies, radio equipment, and electronic oscillators.

  • Specifications: Custom inductor is characterized by its inductance (measured in henries), current rating, resistance (DCR), and self-resonant frequency.

  • Design and Limitations: Designing with custom inductors requires consideration of factors like operating frequency and required inductance. However, these custom inductors can be large, generate heat, and have losses due to resistance.

Tips for Inductor Selection

Tips for Inductor Selection

Choosing the right custom inductor involves considering several factors for custom inductor suppliers. First, identify the required inductance and current rating for your circuit. Next, consider the operating frequency and ensure custom inductors can handle it. Also, take into account the physical size and mounting type. Lastly, consider the custom inductor's cost, quality and reliability.

Custom Inductor Working Principle

Custom Inductor Working Principle

A custom inductor is a passive electronic component that stores energy in its magnetic field. This type of electronic component wholesale is typically made of a coil of conducting wire. The working principle of custom inductors is based on Faraday's law of electromagnetic induction, which states that a change in the magnetic field within a loop of wire induces an electromotive force (EMF) in the wire.


When an electric current passes through the custom inductor, it creates a magnetic field around the coil. If the current changes, the magnetic field also changes, inducing a voltage across the coil. This induced voltage opposes the change in current, a phenomenon known as inductance.


In essence, an inductor for sale resists changes in current and acts as a form of electrical inertia. This property is used in various applications, such as filtering out high-frequency noise in power supplies, tuning circuits in radio and TV receivers, and in transformers to transfer energy between two circuits.


The Role of Custom Inductors in Electronic Circuits

Custom inductors play a crucial role in electronic circuits and have a wide range of applications. Here are some of the key roles they play:

In summary, custom inductors are vital inductive charging components in electronic circuits, with their ability to store energy, filter signals, tune frequencies, and protect against voltage surges.

  • Energy Storage: The custom Inductor stores energy in the form of a magnetic field when an electric current passes through it. This stored energy can be released back into the circuit when needed.

  • Filtering: In power supplies, these custom inductors are used as filters to smooth out the direct current output. They can remove the alternating current components from the signal, allowing only the direct current to pass through.

  • Tuning: Inductors are used by custom inductor manufacturer in tuning circuits such as those found in radios and televisions. They can be used in combination with capacitors to create circuits that resonate at specific frequencies, allowing certain frequencies to be selected or rejected.

  • Choke:  Custom Inductors used as chokes in electronic circuits to block higher frequencies. A choke is an custom inductor designed specifically for blocking high frequencies while passing direct current (DC) and lower frequencies.

  • Delay and Phase Shift: Custom inductors can delay and phase shift alternating current signals. The delay is due to the time it takes to build up and collapse the magnetic field.

  • Surge Protection: Inductors provided by inductor suppliers can protect circuits from voltage surges. When a voltage surge occurs, the custom inductor resists the sudden change in current, helping to protect the rest of the circuit.

  • Transformers: Inductors are used by inductor manufacturer in transformers to step up or step down the voltage levels. Two inductors are used in a transformer, one for the input (primary) and one for the output (secondary).

Inductor Materials That Our Custom Inductor Manufacturer Need

Custom inductor manufacturers require several key materials to produce high-quality custom inductors. 

  • The primary inductor material is a conductive wire, usually made of copper due to its excellent electrical conductivity. This wire is wound into a coil to form custom inductors.

  • The magnetic core material around which the wire is wound is also crucial. It can be air, ferrite, iron, or other magnetic materials, depending on the application. Ferrite cores are commonly used for high-frequency applications, while iron cores are used for low-frequency applications.


  • Insulation materials are also needed to prevent short circuits between the coil turns and to protect the inductor for sale from environmental factors.


  • Inductor suppliers may require various mounting hardware and connectors, depending on the type of inductor being produced.


  • Custom inductor manufacturers need access to high-quality solder and flux for attaching the custom inductor to a circuit board or other components. These materials must meet industry standards to ensure the reliability and longevity of the inductor.
