Introduction to Fixed Inductors

Fixed inductors are electronic components that store energy in the form of a magnetic field. They consist of wire coils wound around a core and are used in circuits for various applications. Fixed inductors come in a multitude of sizes, core materials, and operating parameters.

The VLF302515MT-4R7M-CA Fixed Inductor

The VLF302515MT-4R7M-CA is a 4.7µH fixed inductor produced by Vishay Intertechnology. This specific model is a lead-style power inductor, and its core is made of ferrite with a maximum DC current rating of 2.7A. It comes in a 3.5mm x 10mm package, with a shielding factor of 7, a temperature rating of -40 to +125°C, and a saturation current rating of 10.2A.

Application Fields

The VLF302515MT-4R7M-CA fixed inductor is designed primarily for use in power circuits. It can be used in cellphone chargers, LED power supply systems, and automotive infotainment systems. It is also suitable for portable electronic devices that require high power conversion and efficient energy storage.

Working Principle

The working principle of the VLF302515MT-4R7M-CA fixed inductor is based on Faraday’s Law of induction. When a steady direct current (DC) flows through the coil, it creates a magnetic field around the core. This field stores energy and opposes any changes to the current. This is the basis of its inductive power operation.In addition, when an alternating current (AC) flows through the coil, it induces a voltage in the coil, which can be used to increase the output voltage of a power supply. This is known as AC inductive power operation.

Conclusion

The VLF302515MT-4R7M-CA fixed inductor is an appropriate and useful component for power circuits. It is designed primarily for use in cellphone chargers, LED power supply systems, automotive infotainment systems, and portable electronic devices. By understanding its working principle, users will be able to effectively employ this indispensable component for their applications.
