Fixed Inductors - CDR125-390MC application field and working principle

Inductors are electrical components that are used in various circuits to store energy in the form of a magnetic field. When current flows through the inductor, a magnetic field is created, which then creates an opposing voltage to oppose the flow of the current. This opposition is called inductance, and it is measured in henries (H). Fixed Inductors are one of the most commonly used inductors in various applications. In this article, the focus will be on CDR125-390MC - its application field and working principle.The CDR125-390MC is a fixed inductor of the type CDR125-390MT which is applied in small and medium-sized electronics applications. The device is a high-performance chip inductor which offers low DC resistance, excellent high-frequency capability, high self-resonance, good heat dissipation and thermal stability. It is made of a ferrite core and metal winding. The ferrite core provides the inductance, while the metal winding provides the necessary capacitance to add high frequency characteristics.The CDR125-390MC can be used for various applications in electronic devices such as LED lighting, power management, communication systems, portable consumer electronics, etc. The inductor is also suitable for communication media such as wireless networks, cellular telephones, satellite receivers, and Wi-Fi systems. In addition, the device is also used in other industrial and automotive applications. The typical working principle of the CDR125-390MC is based on Faraday\'s Law. This states that the induction of an electric current in a closed circuit is proportional to the rate of change of magnetic flux. When a magnetic field is applied to the inductor, a counterforce is created. This counterforce opposes further changes in the magnetic field, which results in an opposing voltage being induced. In more complex circuitry, the counterforce must be balanced so that any further changes in the magnetic field are prevented. This is usually done by adjusting the amount of capacitor used. The capacitor stores charge and is able to assist the inductor in retaining its magnetic field.Another important principle of working of the CDR125-390MC is the principle of saturation. As the current passing through the inductor increases, its magnetic field increases correspondingly. If the current passes a certain threshold, the inductor will become saturated. This means that the inductor can no longer create a magnetic field and the current is unable to flow through it. Thus, the inductor must be kept under control by limiting the current passing through it.In conclusion, the CDR125-390MC is a fixed inductor with a ferrite core and metal winding. This device is particularly suitable for small and medium-sized electronics applications. Its working is based on Faraday\'s Law and the principle of saturation. The inductor is used in various applications such as LED lighting, power management, communication systems and automotive applications.
