Fixed Inductors

Inductors are electronic components that store energy in the form of electric or magnetic fields whether in a stationary or dynamic state. The IMC1210EB820J is an example of a fixed inductor, specifically a surface-mount, molded one.

The IMC1210EB820J

The IMC1210EB820J is a fixed, enclosed, molded inductor with a ferrite-core. It has an inductance of 8.2 μH, a tolerance of 20 % and an operating temperature range between -40 ˚C and +125 ˚C. The maximum DC resistance is 0.175 Ω and it is rated for a maximum current capacity of 2,3 Amps. It is also Shock and Vibration Proof, providing extra ruggedness.

Application Fields

The IMC1210EB820J is mainly used to reduce signal and power noise in audio amplifiers, power supplies, DC to DC converters and other switch-mode power converters, as well as general-purpose electronic circuits.Most of these applications involve low frequency signals. Consequently, the typical values of the IMC1210EB820J inductor are usually suitable for these frequencies.Additionally, it is extremely resistant to shock and vibration which makes it suitable for applications in environments subjected to considerable levels of mechanical stress.

Working Principle

When a current passes through a conventional inductor, it creates a magnetic field around it. This field stores energy and acts as a buffer between the electrical source and the load, smoothing current ripples or voltage spikes.The constant opposition to electrical change is known as inductance which, in the case of the IMC1210EB820J, is 8.2 μH.Considering that the size of the mechanical package of this inductor is approximately 12.3 mm x 10.2 mm x 6.8mm, a higher inductance or current capacity would need to be provided by larger mounted inductor component types.

Conclusion

The IMC1210EB820J is a fixed, surface-mount, molded inductor featuring a ferrite-core, 8.2 μH of inductance, 0.175 Ω of DC resistance and a maximum current capacity of 2,3 Amps. It is mainly used to reduce signal and power noise in audio amplifiers, power supplies, DC to DC converters and other switch-mode power converters, as well as general purpose electronic circuits. It is also suitable for use in environments subjected to mechanical stress due to its Shock and Vibration Proof design. Lastly, it works by creating a magnetic field around it in order to provide the required buffer between the electrical source and the load.
