They can also be used in the ferrite rod antenna designed for medium wave receivers.
They can be used at both medium and high frequencies.
They can be used in power transformers that operate in a low frequency range between 1 to 200 kHz.
Ferrite Core inductors can be used in coils that are operated between a frequency range from AF to 100 MHZ.
High inductance - Attained by using ferrite materials with high permeability.
Minimum Stray Field - Use of toroid or pot core.
Performance over temperature - Closely controlled µi (initial permeability) versus temperature.
High Quality Factor - Material with low core losses gapped ferrite core structure.
They allow DC (Direct Current) but not AC (Alternating Current) to pass through them at higher frequencies.
They change electrical energy into magnetic energy and store the energy in them.
In ferrite core inductors, the current passes to generate a magnetic field and the change in magnetic field results in the passing of an opposing current.
Characteristics of Ferrite Core Inductors Out of the two core losses, the hysteresis loss is the dominant one but up to a frequency level that depends on the performance of the cores, beyond which eddy current loss predominates. The eddy current losses in the inductors increases exponentially while the hysteresis loss increases linearly with the increase in frequency and flux. Ferrite Core Inductor LossesĮlectronic engineers prefer to use ferrite core inductors because of the losses they exhibit and their dependence on frequency levels. They contribute in producing electronic circuits of superior quality. Thus, ferrite core inductors boast of high inductance as compared to other inductors with air cores.Īlso, inductors are a major type of passive linear circuit element besides capacitors and resistors. Usually, the permeability level in the ferrite core inductors ranges between 1400 to 15,000, depending on the type of ferrite material used. It leads to an increase in their magnetic field and inductance. Using Ferrite cores in inductors helps to improve the performance of the inductors by providing high permeability to the coil. While using ferrite cores in inductors, we consider the following things. These currents circulate within the inductors alongside the closed-loop of electric current.įerrite core inductors are used in a range of electric circuit applications including power conversion, broadband, and interference suppression. When these solid metal cores are used in inductors, the changing magnetic field exhibits large eddy currents because of the electrical conductivity of the metal. Inductors that are manufactured with a ferrite core inside their coil are Ferrite core inductors. In this article, we’re going to share with you some important information about ferrite core inductors, their characteristics, and their applications. Therefore, ferrite core inductors are popular and considered a better way out to avoid this problem. However, ferrite core inductors have a fixed value, high permeability, and high inductance. The air core and iron core inductors carry low inductance, minimal frequency operations, and higher losses. Usually, there are three types of inductors seen in the market. Hence, inductors oppose any change in current passing through them. When electricity flows into this coil from left-to-right direction, a magnetic field is generated in the clockwise direction. They are made using an insulated wire wound into a coil. Inductors are an electronic component that store electrical energy in a magnetic field when electrical current passes through.
