Top 12 Inductor Manufacturers in 2024

Standard circuit inductors are passive components found in electrical circuits that store energy in a magnetic field. They are used to manage current in a circuit by restricting the pace at which it changes. They can also be used to filter or isolate electrical signals at specific frequencies and to adjust voltage in power circuits. Standard circuit inductors are used in a wide range of electronic devices and equipment, such as power supply, RF circuits, and switch mode power supplies (SMPS). Let's take a look at the world's well-known inductor manufacturers.

How to Select an Inductor

The appropriate inductor is mainly determined based on the package size of the inductor, the minimum inductance value and rated operating current required by the circuit design, etc. In addition, the working environment of the inductor needs to be considered comprehensively, referring to parameters such as working frequency and working voltage.

• The inductor value should be the same as the circuit requirement, especially the inductance value of the coil of the tuning circuit should be accurate.
• Depending on the application, each characteristic may be a factor that needs to be considered and determines other characteristics.
• For inductors with dielectric strength requirements, it is necessary to select packaging materials with high voltage resistance. Usually, inductors with good voltage resistance have good moisture resistance. The use of resin impregnation, encapsulation, and die-casting processes can meet this requirement.
• The main considerations for inductor leads or pins are tension, torsion, welding resistance, and weldability. When the component has been out of the factory for more than six months, the weldability test should be re-performed to ensure the reliability of welding.
• Choose suitable inductor manufacturers. Inductors are high-precision products, which have high requirements for the manufacturer's technology, experience, and control.

The effects of choosing an inappropriate inductor

If an inappropriate inductor is chosen, the basic energy storage and filtering functions of the inductor cannot be achieved, or it may cause a short circuit or leakage in the circuit. In more serious cases, the inductor may heat up and even cause the circuit board to self-ignite, affecting the use of the circuit.
