Fixed inductors are passive devices that store energy using a magnetic field produced from a coil of wire. They typically come in several shapes and sizes, one of the more commonly used types being the HM62-3214150MLFTR. A fixed inductor such as the HM62-3214150MLFTR has a wide range of applications within the electrical engineering and communication field.

Applications

HM62-3214150MLFTRs are mainly used for electronic filtration, tuning, and coupling applications. In filtration, an inductor helps filter out spurious frequencies which may interfere with the signal being transmitted or received. This can include both high and low-frequency interference, as the inductor can block either type depending on its inductance. Tuning applications for fixed inductors include radio and landline communications, where an inductor that is tuned specifically for a frequency ensures the signal is at its clearest when transmitted.

In coupling applications where two circuits must be connected together, such as an amplifier and a speaker, the inductor helps to impart the correct amount of energy between both circuits, dependent on the inductance value. The HM62-3214150MLFTR is often used in this application as it can handle up to 18 A of current.

Working Principle

The working principle of a fixed inductor such as the HM62-3214150MLFTR is based upon the electromagnetic induction principle, which states that an electric current generates a magnetic field and vice versa. When an inductor is connected to an alternating current (AC) circuit, the impedance across the inductor will vary according to the frequency of the current. This is because the magnetic field that the inductor coil produces will be at its strongest for a given frequency, this being known as the resonant frequency. The resulting impedance at the resonant frequency, and also all frequencies above it, will be greater than the impedance at all other frequencies.

When connected to a DC circuit, an inductor will act as a short and will not alter the voltage in any way, as the current in a DC circuit, does not change with frequency. This means that the impedance across an inductor in a DC circuit is 0 Ω.

The HM62-3214150MLFTR is designed to operate in AC circuits with a current frequency of between 10-100 Mhz. It has an inductance of 300 µH, a DC resistance of 1.24 Ω, and a maximum DC current rating of 18 A.

Conclusion

Fixed inductors are widely used components in many electronic applications. A prime example of such an inductor is the HM62-3214150MLFTR. This inductor is widely used in tuning, filtration, and coupling applications, and each of these applications is made possible due to the inductor’s ability to alter the voltage of an AC signal in accordance to its frequency. With a current rating of up to 18 A and a maximum frequency of 100 Mhz, the HM62-3214150MLFTR is ideal for a wide range of applications.
