Introduction
Fixed Inductors are passive devices that are designed to store energy in the form of magnetic field. They consist of a coil of insulated wire wrapped around a non-conductive core, typically made of ferrite or Iron powder. The number of turns of the coil will determine the inductance of the device, as the magnetic field produced increases with a larger number of turns and decreases with a fewer number of turns. The inductance of the device is measured in Henrys (H). Inductors are mainly used in filter circuits, frequency selectors, oscillators and other circuitry designed to operate at specific frequencies. They are also used in voltage limiting and current limiting applications as well as tuning circuits.1812-104H Application Field and Working Principle
The 1812-104H Fixed Inductor is a cylindrical coil made of electroplated copper with an iron core. It has a rated inductance of 104H, and is sized to suit the 1812 case standard, meaning its outer diameter is 2.50mm, and its total length is 4.7mm. This particular inductor is usually used in high frequency applications such as radio transmitters and receivers.When an alternating current is applied to the 1812-104H, the current will cause a varying magnetic field, which in turn induces varying electric current in the nearby inductor. The size of the magnetic field generated depends on the number of turns in the coil as well as the core material used. In this particular case, the iron core provides an effective way to store the magnetic field created, thereby increasing the inductance of the device. The 1812-104H can also be used as an effective low-pass filter. This filter will block all signals above a certain frequency (known as the cut-off frequency), while allowing signals below the cut-off frequency to pass through. The cut-off frequency can be determined by dividing the inductance of the device by the capacitance that is used in conjunction with the inductor.When used in combination with other electronic components, the 1812-104H can be an incredibly useful device. It can be used to create amplifiers, power supplies, filters and many other electronics.Conclusion
In conclusion, the 1812-104H Fixed Inductor is a widely used device in radio and other high-frequency applications. It consists of a coil with an iron core and is rated at 104H. The inductor can be used to block signals of a certain frequency (by creating a low-pass filter) and when used in conjunction with other electronic components, can be used to create amplifiers, power supplies and filters.
