Fixed Inductors

Fixed inductors are components belonging to the passive electronic devices family. They have an inductance value that stays constant, which is why they go by the name fixed inductors. Fixed Inductors are mostly used to filter currents and to store energy in its coils. In this article, we will discuss the application field and working principle of the SC43-3R3 component in detail.

Application Field

SC43-3R3 fixed inductor is a power inductor with high performance and high saturation flux density (4000 GHz?cm). Due to its high saturation flux density, it is suitable for various power applications such as digital display, power adapter, LED driver, switching power supply, DC-DC converter, and notebook computers. SC43-3R3 is a self-shielding fixed inductor that consists of tin-plated iron cores and an enameled wire wound in a square shape. It has good thermal characteristics and mechanical stability which makes it suitable for long-term and accurate use. The SC43-3R3 also has a wide range of inductance values ranging from TOF3.3µH to sF50µH which makes it a great choice for various applications.

Working Principle

The basic working principle of a fixed inductor is based on Faraday\'s law of induction. This law states that whenever a changing electric current passes through a conductor, it will induce a Magnetic field around the conductor.The SC43-3R3 consists of a coil wrapped around a ferrite core. When a current passes through the coil, a magnetic field is induced in the core, and this magnetic field is what generates the inductance. This inductance is proportional to the number of coils in the inductor.The SC43-3R3 also has high saturation flux density which gives it the ability to maintain its inductance even under extreme current conditions. This makes it suitable for high frequency and high power applications where high currents are likely to be encountered.

Conclusion

The SC43-3R3 fixed inductor is a high performance component suitable for a wide range of power applications. It consists of a coil wrapped around a ferrite core which generates an inductance based on Faraday\'s law of induction. It also has high saturation flux density which makes it suitable for high frequency and high power applications.
