4922R-49J

Fixed Inductors

The 4922R-49J is a type of fixed inductor, one of the main components in electronic circuits. An inductor is a type of passive two terminals device which stores energy in the form of magnetic field when electric current is passed through it. Fixed inductors can typically be found in various applications such as signal rectification, power supplies, radio frequency circuits, tuned circuits, and noise suppressors.

application field

The 4922R-49J is most commonly used for DC and low frequency operations in a range between 0 to 100MHz. It is mainly used in voltage regulation, high frequency induction heaters, impedance matching for radio transmitters, and as line filters in power supplies. In addition, it is also used in pulse generation circuits to control the frequency and shape of the pulses.

Working Principle

A fixed inductor works against a change in electrical current in the same way that a condenser works against a change in voltage. As amperes flow through the inductor, a magnetic field is created. This magnetic field increases in strength as long as current continues to flow, and the amount of current flowing is proportional to the magnetic field’s strength. As a result, the inductor resists changes in the flow of current, as increasing current will cause an increase in the inductor\'s magnetic field, opposing the change.

The fixed inductor also works to maintain its magnetic field strength as electricity passes through it. This property is known as inductance and is measured in Henries, or H. Inductance is calculated by dividing the increase in magnetic field strength by the amount of electric current that causes the change. When electric current increases, the magnetic field strength also increases, and more current will be needed to create a stronger magnetic field. This means that as electric current passes through an inductor, the amount of electric current must be constantly increased in order to maintain a constant magnetic field.

Fixed inductors are typically designed to be as small and lightweight as possible in order to conserve electrical energy and reduce costs. They are typically constructed from copper wire wound around a ferrite core, which is surrounded by a magnetic cover. This helps to reduce the size and weight of the inductor and make it more efficient.

In summary, the 4922R-49J is a type of fixed inductor that is most commonly used for low frequency operations in a range between 0 to 100MHz. It is mainly used for voltage regulation, high frequency induction heaters, impedance matching for radio transmitters, and as line filters in power supplies. It works against a change in electrical current in the same way as a condenser works against a change in voltage, and is typically constructed from copper wire wound around a ferrite core.
