Fixed Inductors

An 1812-470M fixed inductor is an electronic component with specific inductance values that remains unchanged even when exposed to a changing magnetic field. It is mainly used for signal filtering and related applications and works on the principle of electromagnetic induction.

Application Field

1812-470M fixed inductors are very commonly used in signal filtering and related applications. This type of inductor is ideal for use in circuits where a large, consistent inductance is required, such as in audio filtering, power supplies, and blocking applications. They can also be used in RF circuits, particularly at low frequencies, and for pulse transformers.

The 1812-470M fixed inductor also has applications in radio frequency circuits because of its high Q factor. Its small size and high current handling capabilities make it suitable for use in portable devices, where space is limited and its minimal power loss is of great advantage. In addition, it can be used in circuits that require a combination of voltage, current, and inductance.

Working Principle

The 1812-470M fixed inductor operates on the principle of electromagnetic induction. Electromagnetic induction is the process in which an electric current is induced in a wire by the presence of a changing magnetic field or a changing electric current. As the current passing through the wire is increased, it produces a magnetic field around it, and this field then induces an electric current into a nearby circuit.

In the 1812-470M fixed inductor, the inductance is provided by a coil of insulated wire wound around a core material made of either iron or ferrite. When electric current passes through the wire in the coil, a magnetic field is produced and a reverse current is induced in the nearby circuit. The magnitude of this reverse current is determined by the inductance of the coil and the magnitude of the current passing through it.

The 1812-470M fixed inductor is a passive component, meaning that it does not require any external power to operate. Its operation is based solely on the magnetic field created by the current passing through it and the induced current flowing in the circuit. As such, it is considered to be electrically silent and does not produce any noise or harmful emissions.

The 1812-470M fixed inductor is an incredibly useful component, with numerous applications across many different industries. Its small size, low power loss, and high stability make it an ideal component for portable devices, audio filters, RF circuits, pulse transformers, and other applications where a consistent and reliable inductance is required.
