0402-47NK

Fixed inductors are one of the most common types of electrical components, and are widely used in a variety of applications. 0402-47NK is one of a series of inductors tailor-made for specific applications. This article will discuss the application field and working principle of 0402-47 NK fixed inductors.

Fixed inductors, also known as choke coils, are electrical components that store energy in the form of a magnetic field. When current passes through an inductor, the magnetic field generated by it builds up over time, storing energy. This magnetic field will collapse when the current passing through it decreases, releasing the energy it stored back into the circuit.

0402-47NK fixed inductors are specifically designed for use in consumer electronics and medical equipment. This type of inductor is designed to have a low profile, measuring in at only 4 mm by 2 mm. It has a high saturation flux, making it ideal for applications requiring low DC resistance. It is also designed to have low temperature coefficient, so it can be used in applications needing stable performance.

The working principle of a 0402-47NK fixed inductor is based on Faraday\'s Law of Induction, which states that an electromotive force is generated in a conductor whenever the magnetic field around it changes. When current passes through the inductor\'s coil, it creates a magnetic field which builds up over time, storing energy. This energy is released back into the circuit when the current decreases. The inductor also acts as an obstacle to the flow of alternating current, allowing the current to flow through it at specific frequencies.

In conclusion, 0402-47NK fixed inductors are electrical components designed for consumer electronics and medical equipment, and have a low profile measuring at 4 mm by 2 mm. The working principle of this inductor is based on Faraday\'s Law of Induction, and it allows current to flow through itself at specific frequencies, as well as acting as an obstacle to the flow of alternating current. This type of inductor is popular due to its low temperature coefficient and high saturation flux, making it ideal for applications requiring stability and low DC resistance.
