S1812R-474F

Fixed inductors are devices that store energy in the form of a magnetic field. The S1812R-474F is a type of fixed inductor commonly used in a variety of applications, such as AC/DC converters, power supplies, motor drives, and power factor correction just to name a few. This particular model is composed of ferrite core and copper wire in a radial EB-L type package.

In order to understand how the S1812R-474F operates, it is first important to understand the basic working principles of inductors. An inductor is a passive two-terminal electrical device that stores energy in a magnetic field when an electric current flows through it. When a voltage is applied across the terminals, a current begins to flow. This current produces a magnetic field around the windings of wire, which then stores energy.

When the voltage is removed from across the terminals, the magnetic field also collapses, thus releasing the energy stored in the magnetic field back into the circuit. The amount of inductance is determined by the number of turns of wire and the type of core material that is used, with ferrite cores typically being the most popular choice.

The S1812R-474F has a rated inductance of 0.47 microhenries, and a maximum DC current rating of 1.4 amperes. It has an operating temperature range of -20 to +80 degrees Celsius. The body size is 31 millimetres long with a 9.6 millimetres diameter. It has a rated SRF of 800 MHz, and the insulation resistance is listed as 10 milliamps.

As for applications, this model fixed inductor can be used in a variety of power supply designs. For instance, it can be used as a choke or filter for power factor correction circuits, to reduce input current ripple, or to block higher frequencies while allowing lower DC current to pass through. Additionally, it can be used in AC/DC converter designs such as buck, boost, or flyback topologies. In motor drive designs, the S1812R-474F can be used as a filter choke to reduce unwanted noise and spikes, or as an output filter to reduce harmonic distortion.

Finally, the S1812R-474F can also be used in RF designs, as it can effectively block out high frequency signals while allowing the desired low frequency signals to pass through. With its compact size and suitable performance characteristics, the S1812R-474F is a popular choice for a variety of applications, ranging from power supply designs to RF designs.

In conclusion, the S1812R-474F is an ideal choice for those needing a fixed inductor in a variety of applications. With its ferrite core and copper wire, it is capable of storing and releasing energy in a magnetic field when a voltage is applied or removed. Additionally, its compact size and versatile performance make it a popular choice for power supply and RF designs.
