Fixed Inductors: S0402-47NF2S Application Field and Working Principle

Fixed inductors are vital components in electrical and electronic circuit boards. They make up an integral part of the basic components used for a wide array of devices which include radios, computers, and other consumer and industrial equipment. The S0402-47NF2S fixed inductor is a robust and reliable part in this product line up. This article will address the application field and working principle of the S0402-47NF2S fixed inductor.The S0402-47NF2S is a four terminal surface-mount fixed inductor which is used in a wide variety of applications. Owing to its small size and low ESR characteristics, this part is most suitable for use in portable devices where a high degree of efficiency is required. Its working frequency ranges from 1 MHz—100 MHz, making it ideal for applications involving radio and communication systems.The S0402-47NF2S is composed of a number of components. These include a ferrite core, a few turns of copper foil, a plastic case, and several ferromagnetic conjoining bobbins. The ferrite core is used to generate a narrow-band signal in response to the current passing through it. The copper foil is used to conduct the current, while the plastic case shelters the components from corrosion. The ferromagnetic bobbins are used to link the main coil to the terminals, allowing the induction to take place.The S0402-47NF2S fixed inductor operates on the principle of electromagnetic induction. When a passing current enters the inductor, a magnetic field is induced around it. This magnetic field then attracts magnetic particles within the ferrite core, resulting in a resonance. And this resonance creates a narrow-band signal which then propagates through the copper foil. The signal is then directed towards the ferromagnetic bobbins, and from there, it is directed to the terminals.The S0402-47NF2S fixed inductor is a very reliable and general-purpose part. It is capable of producing a strong and clear signal with minimal additional interference. Furthermore, its small form factor and low ESR characteristics make it ideal for use in portable devices. This part has an operating temperature which ranges from –40°C to +105°C, and can easily withstand a wide variety of adverse conditions.In conclusion, the S0402-47NF2S fixed inductor is a small, highly reliable component. It produces a strong and clear signal which is capable of withstanding a wide range of environmental conditions. It is ideal for use in portable devices, and its low ESR characteristics make it a great choice for applications involving radio and communication systems.
