MILS1812R-821K

Fixed Inductors

Fixed inductors play an important part in a variety of electronic circuits, such as filters, power supplies and oscillators. They are types of inductors which feature a fixed inductance, which means that they can not be altered without external intervention. The MILS1812R-821K is one of the most popular inductors used in today’s electronic applications. This article explores the applications and working principle of the MILS1812R-821K fixed inductor.

MILS1812R-821K application field

The MILS1812R-821K fixed inductor is primarily used in AC-DC power supplies. It is commonly employed in applications such as inverters, switch-mode power supplies, and other power supplies which require high accuracy filtering and conversion. Furthermore, the MILS1812R-821K inductor is also suitable for use in audio-visual and Hi-Fi equipment, where precision and stability are essential.

MILS1812R-821K Working Principle

The working principle of the MILS1812R-821K fixed inductor involves the use of magnetic fields. An inductor is a passive two-terminal electrical component with an output voltage that is proportional to the rate of change of the current input. When an inductor is placed in an alternating current source, it creates a magnetic flux that induces a voltage in the opposite direction, as an opposing force. The opposing voltage is known as a back EMF, and it helps to regulate and smooth out the input current.

At the same time, the inductor acts as a filter element, which helps to block signals of certain frequencies while allowing signals of other frequencies to pass through. As a result, the MILS1812R-821K fixed inductor acts as an effective filter for AC-DC power supplies, providing stable and precise power.

Conclusion

In conclusion, the MILS1812R-821K fixed inductor is an important component in AC-DC power supplies, especially for applications where precision and stability are necessary. It works by generating a back EMF in response to current input, as well as providing an effective filtering element to block signals of certain frequencies. Thanks to its reliable performance and compact size, the MILS1812R-821K is highly suitable for use in audio-visual and Hi-Fi equipment.
