Fixed Inductors

Inductors are a type of electronic component that, like resistors and capacitors, are used in a variety of electronics applications. They differ from other components in that they store energy in the form of magnetic fields. The different types of inductors, including the B82144B2154J000, have distinct application fields and working principles which vary from each other.

Description of B82144B2154J000

The B82144B2154J000 is an SMD fixed inductor from the B82144 series. Its inductance is 2.15mH, and it has a rated current of 1A. It is made of molded and encapsulated plastic with a rectangular-shaped body. The device size is 3.2 x 3.2 x 4.3mm. Its operating temperature range is from -40°C to 125°C.

Application Field of the B82144B2154J000

The B82144B2154J000 has a wide range of uses in a variety of applications. It is designed for use in 12V to 24V switching power supplies, DC-DC converters, and other circuits in consumer electronics such as mobile phones, multimedia devices, gaming systems, and personal computers. It can also be used in high-end audio amplifiers, automotive, LED lighting, lighting systems, medical devices, and robots.

Working Principle of the B82144B2154J000

The B82144B2154J000 operates on the principle of inductance. When an electric current passes through this type of inductor, it creates a magnetic field. When the current is removed, the magnetic field dissipates and its energy is stored in the form of an electromagnetic field. This stored energy is transformed back into electrical current when needed. The inductance of the B82144B2154J000 means that the amount of electrical energy stored in its core is proportional to the amount of current passing through it.

When used, this inductor acts as a filter in power circuits by limiting the frequency of the passage of electrical signals. The higher its inductance, the lower the frequencies that will be passed through, and the better the inductor is at eliminating unwanted frequencies. This type of inductor is also ideal for stabilizing the output voltage of power circuits.

Limitations of the B82144B2154J000

The B82144B2154J000 has certain limitations. One limitation is that it cannot be used in very high frequency applications, as the core losses start to become significant at higher frequencies. It is also not suitable for use in applications that require high accuracy, as the variation in parameters can cause a shift in the frequency response. The temperature range of the device is also limited, as it must not be used below -40°C or higher than 125°C.

Conclusion

The B82144B2154J000 is a type of fixed inductor, which is commonly used in consumer electronics, automotive, audio, and medical device applications. It works on the principle of inductance, storing energy in the form of a magnetic field, and releasing it back as an electrical current when needed. It acts as a filter, eliminating unwanted frequencies, and is useful for stabilizing voltage. It has some limitations, such as operating temperature range and a lower frequency limit, but overall, it is a very useful electronic component.
