Fixed Inductors

The IMC1812BNR56J Inductor is a type of fixed inductor, which is a component that stores energy in the form of a magnetic field when a current flows through it. It plays a vital role in countless electronic circuits, from radio frequency applications to switching power supplies. This article will provide an overview of the IMC1812BNR56J, including its typical applications and working principle.

Application of the IMC1812BNR56J

The IMC1812BNR56J is a type of fixed inductor used in various electronic components and devices. Typically, its application field is in RF (radio frequency) designs since it helps with keeping harmonics of different frequencies from entering the circuit. Additionally, they are also used as differential mode filters to suppress common mode interference from both power and data lines. Lastly, these inductors are used to reduce radiated emissions from power and data cables and in general, they provide a means of impedance matching. Each of these applications require different levels of inductance, and as a result, the specific inductance of each type of inductor must be taken into consideration when selecting one.

Working Principle of the IMC1812BNR56J

The IMC1812BNR56J features a ferrite core that is encased by wire coils. This is essential for the inductor to store energy in the form of a magnetic field. When an alternating current is passed through the coil, the alternating current will cause the magnetic field to also vary with time. This then induces an electromotive force in the circuit, which is called the back EMF. The back EMF helps to resist the current in the circuit itself and helps in controlling the magnitude of the current, ensuring it doesn’t exceed the safety limits. As a result of the induced EMF, there will be a voltage drop across the inductor, which is proportional to the frequency of the current.

Specifications of the IMC1812BNR56J

The IMC1812BNR56J is a fixed inductor with a low DCR, low inductance, and superior temperature stability. It features a ferrite core encased in a wire coil, with a DCR ranging from 16-50mΩ, inductance ranging from 1.75mH-2.45mH, and an operating temperature of -40°C to +125°C. In addition to these specific numbers, the inductor also features excellent frequency response, low profile, and low EMI (electromagnetic interference).

Conclusion

Overall, the IMC1812BNR56J is a type of fixed inductor that is widely used in various electronic components and devices. Its primary applications included RF designs, differential mode filters, and radiated emission reduction. The inductor itself is made up of a ferrite core encased in a coil, with a low DCR and excellent frequency response.
