Fixed Inductors

Fixed inductors are electronic components used to store energy in the form of a magnetic field. Typically, fixed inductors consist of a coil of wire wrapped around a core made of either ferrite, iron, or air. There are various types of fixed inductors, from low power through-hole designs to very high power surface-mount varieties. The IMC1812RV121J fixed inductor is a surface-mount device often used in power supply applications.

IMC1812RV121J Application Field

The IMC1812RV121J is a high current surface mount inductor with a maximum current of 20A. It is suitable for a wide range of applications including:

• DC/DC converter buck mode power supply
• DC/AC inverter or synchronous rectifier outputs
• Used as a high current choke
• Overshoot prevention/interference suppression
• Induction heating
• Switching power supplies

As it supports higher currents than other types of fixed inductor, this means the IMC1812RV121J can be used for more demanding applications, such as energy conversion and high efficiency power supplies.

IMC1812RV121J Working Principle

The IMC1812RV121J uses a magnetic field to store energy. Its working principle can be explained by Faraday\'s Law of Induction, which states: an electric current produces a magnetic field, where a changing magnetic field induces a current. This means the IMC1812RV121J is a transducer that converts electric energy to magnetic energy and vice-versa.

In a fixed inductor, the coil of wire is wrapped around ferrite or iron core. When an electric current passes through the wire, a magnetic field is produced inside the core. This produces an opposing magnetic field on the other side of the core that prevents the current from dissipating. The stored energy in the inductor then dissipates slowly when the current is turned off. This produces a sustained smooth current for the application.

The IMC1812RV121J has high heat dissipation and is capable of withstanding high voltage and current. It has a large saturation current of up to 20A, which results in higher total power for the application. Its construction is also designed to reduce power loss due to EMI or other interference.

Conclusion

The IMC1812RV121J is a highly efficient high current surface mount inductor that is suitable for a wide range of applications such as DC/DC converters, DC/AC inverters, choke, and overshoot prevention. Its working principle of Faraday\'s Law of Induction allows it to convert electric energy to magnetic energy and vice-versa. Furthermore, its construction is designed to minimize power loss due to EMI or other interference.
