Fixed inductors are widely used in various applications, including high frequency switching power supplies. The S4924R-391J is also used in such applications, and its application fields and working principle are discussed in this article.

Application Field of S4924R-391J

The S4924R-391J is a radial leaded, low-profile, surface mount fixed inductor. It is generally used in a variety of portable application such as cellular phones, portable audio players, digital cameras, and other mobile or low-power devices. It is also used in high frequency switching power supplies, providing good board-level isolation to extend power supply life. In addition, it is suitable for use in a variety of power electronics applications, where it helps to reduce the noise generated by the power line and reduce the amount of losses.

Working Principle of S4924R-391J

The S4924R-391J is a fixed inductor that uses the principle of magnetic field induction. It consists of an inductor coil, which is surrounded by a steel core. This core creates a magnetic field when it is subjected to an electrical current. This magnetic field is then used to induce a voltage across the inductor. The voltage is then regulated and controlled by using a filter capacitor, in order to produce a smooth output. The voltage produced by the S4924R-391J is regulated to create a specific current in the circuit, which is proportional to the input power.

The inductor works on the principle of Faraday’s law of induction, which states that when a magnetic field is changed, it induces a voltage in a conductor. In other words, the voltage produced in an inductor coil is directly proportional to the rate of change of the magnetic field. This property of inductors is exploited in many applications, including voltage regulation.

Conclusion

The S4924R-391J is a low-profile, surface mount fixed inductor that is used in a variety of applications, including high frequency switching power supplies.
