Fixed inductors are a type of passive electronic component used to store electrical energy in a magnetic field. They can be found in many different applications, including power, telecommunications, consumer products, automotive, and medical. The 1812R-222K is one type of fixed inductor designed for board level applications. In this article, we will look at the application field and working principle of the 1812R-222K.
Applications
The 1812R-222K fixed inductor was specifically designed for board level applications in high-end consumer products and telecommunications. Its high profile allows for surface mount installation and excellent thermal management. Additionally, the 1812R-222K is ideal for stability control in devices that require high input power and output current. As a certified safety component, it is also suitable for medical or automotive applications.
Working Principle
The 1812R-222K fixed inductor works by storing energy in a magnetic field generated by an electrical current in the coil. This magnetic field is created around the hard iron core inside the inductor, which is made up of ferromagnetic materials. As the electrical current is increased, the magnetic field also increases, thus storing more energy in the magnetic field.
When a voltage is applied to the inductor, the stored energy in the magnetic field will cause a current to flow in the inductor, which is known as the inductive current. This inductive current generates an opposing magnetic field that partially cancels out the original magnetic field. As the opposing magnetic field increases, the inductive current gradually decreases until it reaches zero. The energy stored in the inductor is then released in the form of an electric current.
Conclusion
The 1812R-222K fixed inductor is a popular choice for board level applications in consumer products and telecommunications. With its high profile and effective thermal management, it is suitable for high input power and output current stability control. It is also certified for safety, making it an ideal choice for medical or automotive applications. As we have seen, the working principle of the 1812R-222K involves storing energy in a magnetic field and releasing it when a voltage is applied to the inductor.
