Fixed inductors are electronic components which store energy in the form of an electric field or an electric current. They consist of a coil of wire, usually made of copper, wound around a core material, such as iron, ceramic, or resin. The current induced in the coil by an external voltage creates a magnetic field which stores the energy.

The 1812-471H is an inductor typically used in the Power over Ethernet (PoE) interfaces. It is an encapsulated, general purpose, shielded package style power inductor. The 1812-471H is a low profile, 4.7µH, 18.13Ω rated inductor with a 3A maximum rated current specification. It is capable of continuous operation up to a maximum of one hundred twenty-five degrees Celsius.

The 1812-471H is designed for a wide range of application fields, including DC supply line filter, pulse transformer, DC-DC converter, telecom, general power supplies, and uninterruptible power supplies (UPS). The inductor features shielding material to ensure good high frequency performance. It is designed to minimize both Core losses and Coil resistance to achieve high efficiency applications.

The working principle of the 1812-471H inductor is based on the same properties as other inductors. When an external voltage is applied, it creates a current through the winding of the inductor, and the resulting electric field stores the energy. This energy is exerted on any component connected to it, as long as the current remains constant. The inductor is designed to minimize the resistance in the winding so that it can pass through large currents without greatly affecting the voltage.

The current created by the voltage induces a magnetic field surrounding the inductor. This field stores the energy from the current and creates an opposing magnetic field, which opposes any changes in the current. This helps the inductor hold a constant current until the voltage is removed, and the energy is dissipated as heat. This property of inductance is the main reason why inductors are used in a wide range of applications.

The 1812-471H inductor is a great choice for many types of applications. Its ability to pass through large amounts of current with minimal loss of voltage makes it suitable for use in various power over Ethernet interfaces or other power management systems. Its robust design and shielding material makes it ideal for use in environments with high temperature, high voltage, and high frequency requirements.

The 1812-471H is a versatile and reliable inductor. Its stable current passing and energy storing ability make it a great choice for a variety of applications. It is capable of handling high temperature, high voltage, and high frequency requirements, making it suitable for use in a wide range of applications. It is a great choice for those needing a reliable, robust, and cost effective inductor.
