Fixed Inductors

Fixed Inductors are passive electronic components mainly used in electrical and electronic circuits, to limit and store energy. The most common form is the coil and is composed of a wire wound into a roll, attached to the terminals at two ends. The SCB75C-560 is a type of fixed inductor, and in this article, we will take a look into its application field and working principle.

SCB75C-560 Application Field

SCB75C-560 has a wide application range, it is functional in many electronic circuits as a component to the DC-DC converters, DC-AC converters, AC-DC converters, LCD backlighting, small motor drives, switching DC/DC converters, coupled inductors, current-compensating chokes or as filters. Generally speaking, it is mainly used for buck, boost, and flyback converters as well as DC/DC converters in DC/AC applications, such as UPS systems.

SCB75C-560 Working Principles

The SCB75C-560 is composed of a ferrite core and a copper wire. When current flows through the copper wire, a magnetic field is generated inside the ferrite core, limiting and storing energy. The most interesting part is that when the current reduces, the magnetic field breakdown occurs, while a much higher voltage is obtained.

When current is passing through the copper wire, the magnetic flux determines the number of turns and a larger ferrite core is required to increase the inductance. Therefore, the inductance is proportional to the number of turns as well as current. The voltage is proportional to the number of turns according to Faraday\'s law. Additionally, the inductance also has a direct relationship with the capacity of the core material. Thus, by adjusting the core material, ferrite core size, and number of turns, the operating frequency, inductance, and voltage can be optimised for maximum efficacy.

Conclusion

In conclusion, SCB75C-560 is a high performing fixed inductor with wide application range, suitable for various circuitries. The working principle is relatively simple, current passes through the copper wire to the ferrite core to generate magnetic flux. The flux determines the number of turns, thus decides the inductance and voltage. Regulation of core cast material, core size, and the turns can be adjusted to obtain the optimal performance.
