Fixed inductors refer to a special type of inductor which has a fixed inductance. The inductance of such components can range from several nanohenrys to thousands of henrys, depending on the type of inductor. The fixing of inductance enables inductors to be used within circuits with a well-defined frequency cutoff. This makes them the go-to component for applications such as power supplies, filters, radio frequency interference, signal generator circuits and so much more. One such fixed inductor is the Murata S0402-4N7F3B, a surface mount inductor that has 4.7uH at +-30%, 470MHz SRF, and 5.2A current rating. It is a micro SMD power inductor. The S0402-4N7F3B has a number of possible applications in RF electronics and other circuit designs. Due to its high frequency cut off capability it is suitable for use in switched mode power supplies, radio frequency filters and resonant circuits. Its small size and high current rating make it ideal for portable and low power designs. The working principle of the S0402-4N7F3B is straightforward. The inductor works on the principle of electromagnetic induction. When a current is applied to the inductor, a magnetic field is created around it, and this magnetic field induces a voltage across it. This voltage is dependent on the inductance of the inductor. This property of an inductor can be used in a number of ways to achieve the desired effect. One application is in the use of filters. An inductor can be used to pass high frequencies, while blocking out lower frequencies. The inductor’s impedance decreases as frequency increases and so the high frequencies pass through while the low frequencies are blocked. Another application of the inductor is in switch-mode power supplies. This is mainly due to the inductor’s ability to store energy. The inductor can store the energy produced by the power supply, allowing it to be used when needed. This helps to reduce the amount of energy used, which in turn reduces the costs of the power supply. The S0402-4N7F3B is a versatile and powerful fixed inductor that can be used in a variety of applications. It has a high frequency cut off, which makes it suitable for use in RF circuitry. Its small size and high current rating make it ideal for low power designs. It can also be used in the form of a filter or a switch-mode power supply.
