Fixed inductors are widely used in various electrical parts. HF1008R-101J is one of the most popular fixed inductor products in the market. The following article will explain its application field and working principle.

The HF1008R-101J is a kind of axial-leaded inductor, the maximum rated current being up to 1.48A, and it is particularly suitable for use in circuit board. Due to its high current resistance and low DC resistance, HF1008R-101J is capable of generating large amount of power. Therefore, it is often used in power supplies pertaining to consumer electronics, such as computers, cellphones, and tablet PCs.

In addition to its application in power supplies, HF1008R-101J can also be used as a high frequency filter or an electromagnetic interference rate limiter in high-precision signal processing equipment. In order to reduce the external interference, engineers often use this type of inductor in order to reduce the signal distortion.

In terms of its working principle, HF1008R-101J is basically an electromagnetic inductor, which works based on the principle of Faraday\'s Law and Lenz\'s Law. As shown in the figure below, the two main principles involved are the amount of induced current in an inductor and its self-excitation, respectively.

When a conductor is exposed to a changing magnetic field, a current will be induced in the conductor due to Faraday’s Law of Electromagnetic Induction. When the current is big enough, it will create an induced magnetic field opposite to the original field, according to Lenz’s Law. This process will cause the voltage drop, resulting in a low-pass filter.

In addition, HF1008R-101J also has a ferrite core, which ensures that the inductors effectively avoid too much interference from the external environment. In this way, it can meet higher requirements on the stability of inductances.

To sum up, HF1008R-101J is a popular fixed inductor product that has many useful features and wide application field. It is widely used in power supplies, signal processing equipment and many other areas to meet different electrical engineering needs.
