Fixed Inductors

An inductor is an electronic component constructed of a coil of wire and is used to store magnetic energy. It is composed of a conductor in the form of either a coil or helix, usually a metal such as iron or copper or a ferromagnetic core, with air, dielectric, or other insulating material between the winding turns. A fixed inductor, also known as a chock, is a type of inductor whose inductance value cannot be adjusted or changed. The 744029470 is a suspended fixed inductor and its application field and working principle can be summarized as below.

Application Field of 744029470

The 744029470 fixed inductor is suitable for use in DC/DC converters, cell phone\'s antenna feed transceivers, and SMPS applications. It is commonly used as part of voltage-controlled oscillators (VCOs) as well as output filtering in LCD backlighting applications. This type of inductor is also commonly found in solar street lamps and LED signs.

Working Principle

The fixed inductor works according to the Faraday\'s law of induction. This law states that when a conductor passes through a magnetic field, an electric current is induced in the conductor. The magnitude of the induced current depends on the rate of change of the magnetic field. When a current passes through the inductor, the magnetic field generated induces an opposition to the current (Lenz\'s law), resulting in an increase in the voltage drop across the inductor. The voltage drop is proportional to the frequency of the current.

The 744029470 inductor provides a high inductance value of 4.7mH. With this fixed inductor, a high-current density is achievable while keeping its footprint small. It also features effective electromagnetic interference (EMI) suppression and is capable of supporting high bandwidths. This type of inductor is also constructed with high-temperature endurance and a high saturation current.

Conclusion

The 744029470 fixed inductor is a highly useful electronic component that sees extensive use across a variety of DC/DC converters, LED signs, and other electronic systems. Its capability to provide an effective EMI suppression as well as its small size makes it a great choice for many applications. The 744029470 also has excellent performance in terms of its high-temperature endurance and saturation current.
