Fixed inductors, or more commonly referred to as inductors, are an electronic component in electronics that stores energy within a magnetic field and also functions as an AC device. They are often used in the applications for AC power, which involve regulating the current flow in the circuit or even providing the proper orientation of the output current in order to optimize the power efficiency. An example of this application field would be the ILC0402ER1N0S, which is a small and compact inductor.

The ILC0402ER1N0S is a surface-mount fixed Inductor that has a 0.31 A rated current and a 200 mOhm resistive reactance that is suitable for frequencies up to 27 MHz. It is ideal for applications where tight space constraints require a miniature install size and where the inductance value needs to be controlled precisely for product requirements. This inductor incorporates an EMI-shielded core to reduce noise and provides superior EMC performance even in noisy environments.

The specific characteristics of this inductor are also suited to a wide range of elevated temperature protection-levels that can be used in consumer or commercial electronic products. The ILC0402ER1N0S also provides a predictable saving of material and labor costswith its low profile (0.37 mm) and relative insensitivity to mounting torqueeven on sensitive PCBs.

In terms of the working principle, an inductor functions on the principle of electromagnetism, specifically, Faraday’s Law of Induction. When an electric current flows through a wire, it sets up a magnetic field around it. This magnetic field induces its own emf opposing the current in the wire producing its own magnetic field which in turn induces an electric potential of its own, resulting in a change of energy into another form. According to Faraday’s Law of Induction, when the electric current flowing through a wire changes, the voltage potential across the winding of the coil changes, causing the voltage across the inductor to change. This changing voltage across the inductor induces a current that is inversely proportional to the rate of the change in voltage. In other words, the higher the rate of change in the voltage, the greater the current produced, thus producing and storing energy.

The field of application for the ILC0402ER1N0S is broad. With its reliable performance and compliance with higher temperature requirement, it is often used in an array of consumer and commercial electronic products, including portable electronic devices, wireless and data transmission devices, cellular telephone devices, netbooks, digital cameras, and automotive applications. Additionally, its low profile design and insensitivity to mounting torque enable it to be used for computer motherboards.

Overall, the ILC0402ER1N0S is an optimized inductor for applications requiring ultra-small size, shielding, PCB compatibility, and excellent temperature stability. In terms of its working principle, it functions on the principle of Faraday’s Law of Induction which essentially states that when the electric current flowing through a wire changes, the voltage potential across the winding of the coil changes, causing the voltage across the inductor to change, producing and storing energy.
