Inductors are a type of wide-used passive electronic component, and it can be categorized into many varieties according to its specific characteristics and working principles. One of the categories, Fixed Inductors, includes LEM2520T1R2J, which is a kind of surface-mount power inductor. In the following passage, the application field and working principle of LEM2520T1R2J will be discuss.

The main application field of LEM2520T1R2J is the medium and small power consumption equipment, such as digital cameras, smart phones, and so on. It can also be used in power regulation, EMI filtering, and signal filtering, which all require the product to have the excellent performance in terms of size, efficiency, cost, and other power characteristics. In addition, LEM2520T1R2J also has the characteristics of low profile, high current capacity, and high performance.

Basically, LEM2520T1R2J working principle is to convert the input electrical energy into magnetic energy and then back to electrical energy. This mechanism can be broken down into three individual piles: an inductor, a capacitor and an amplifier. First, the input energy is stored in the inductor in the form of magnetic energy. Then, when the capacitor is connected to the inductor, the magnetic energy is released and converted to a changing electric current. Lastly, the amplifier is used to amplify the current, which then flows across the resistor and output the output voltage.

Moreover, in order to increase the power efficiency of LEM2520T1R2J, a feedback mechanism is often applied, which is commonly known as the “floating inductor” method. In this method, the output of the amplifier is used to control the input to the inductor, resulting in a small but effective increase in power efficiency. The feedback is provided by an electronic device called a “voltage regulator”.

In summary, the application field and working principle of LEM2520T1R2J can be said as the usage in medium and small power consumption products such as digital cameras and smart phones, also the usage in power regulation, EMI filtering, and signal filtering, which all has the excellent performance in terms of size, efficiency, cost, and other power characteristics. Besides, its working principle converts the input electrical energy into magnetic energy and then back to electrical energy, which amplified by the amplifier, resulting in a small but effective increase in power efficiency through the feedback mechanism.
