Fixed Inductors
Fixed inductors are electrical components comprising of magnetic cores wound with insulated copper wire and encased in an outer cover. They are often used in electronics applications such as electronic circuits, DC power supplies, voltage stabilizer, potentiometer and timer circuits. Fixed inductors are available in various inductance values ranging from a few uH to thousands of mH.
1840R-30K Application Field and Working Principle
The 1840R-30K is a fixed inductor designed for radio frequency applications. It is used in applications such as radio receivers, cable television amplifiers, radio transmitters, antenna wave guides, modulators and DC power supplies. The 1840R-30K is characterized by its low frequency response and high impedance when operated at frequencies above 1kHz. The core material of the 1840R-30K is ferrite and is designed with a number of windings of copper wire. The number of windings determines the inductance and the resistance of the inductor. The capacitance of the 1840R-30K is extremely low, allowing it to operate in high frequency applications.
The working principle of the 1840R-30K is based on the Faraday’s Law of Electromagnetic Induction. This law states that a current carrying conductor placed in a magnetic field creates an induced voltage across the conductor which is proportional to the rate of change in the magnetic field. The 1840R-30K creates a magnetic field when a current passes through the number of windings. This magnetic field induces an electric flux that generates a voltage at a different point in the circuit. An increase in the number of windings will result in an increase in the inductance. The voltage induced in this manner is proportional to the rate of change of the current on the inductor.
The 1840R-30K fixed inductor is suitable for lower to medium power circuits and is available in compact packages. With its low profile and superior heat dissipation, it is an ideal choice for use in high frequency and power amplification applications. It can also be used as a filter to attenuate undesirable frequencies and reduce interference. In addition, the 1840R-30K is ideal for use in RFI/EMI applications as it exhibits excellent attenuation performance in the range of 100kHz to 30MHz.
In conclusion, the 1840R-30K fixed inductor is a reliable and high performance choice for radio frequency applications. It provides superior performance when operated in high frequency and power amplification circuits. It is also very suitable for use in RFI/EMI applications, providing excellent attenuation performance. With its low profile and excellent heat dissipation, the 1840R-30K is an ideal choice for applications requiring high inductance and impedance.
