Fixed Inductors are often used for several practical applications as they are versatile electric components that act as both conductors and resistors. A widely used type of Fixed Inductors is the SDE1006A-121K. This inductor is most commonly used in power supplies, switch-mode power supplies, and LED lighting applications.

The SDE1006A-121K is a fixed inductor with the inductance value of 12.1uH and saturation current of 8.5A. The peak current resistance is 0.010 Ohms. It is made of a Ferrite core for low noise operation.

The working principle of the SDE1006A-121K relies on Faraday’s Law of electromagnetic induction. This law in its simplest form states that when a conductive material is exposed to a changing magnetic field, electric current is induced in the material. The effect of this induced current is to create a magnetic field which opposes the changing magnetic field. When used in its intended application, the SDE1006A-121K creates an effect that prevents high current flow and regulates the current levels.

When using the SDE1006A-121K in a prototype circuit, it is important to take into account the power rating of the circuit. This is because of the heat generated by the current passing through the SDE1006A-121K. The heat generated by the SDE1006A-121K will reduce the life of the inductor when for example used in a power supply. For this reason, the SDE1006A-121K should be placed in an area that has sufficient air flow for the device to dissipate the generated heat.

In summary, the SDE1006A-121K is a Fixed Inductor which is most widely used in power supplies, switch-mode power supplies, and LED lighting applications where it acts as a regulator of current levels. The inductor works on Faraday’s Law of electromagnetic induction by creating a magnetic field opposing a changing magnetic field. The power rating of the circuit should also be taken into consideration to prevent the SDE1006A-121K from melting due to generated heat.
