Fixed inductors are specialized electrical components designed to limit the flow of electrical current in circuits. These devices are made of active and passive elements and use electromagnetic induction to accomplish their task. An example of a fixed inductor is the S0402-47NF3C, which is used in a variety of industrial and electronic applications.

In terms of construction, the S0402-47NF3C is a 0402 chip form unit with a relatively low profile making it suitable for a variety of space-restrictive applications. It comprises an actuator containing a ferrous core surrounded by an electrical winding. This winding consists of many turns of copper wire, and when a current flows through it, it generates an inductance. This inductance preserves the current’s magnetic field, which allows the current to pass quickly and efficiently when the core is then removed.

In terms of features, the S0402-47NF3C has a maximum inductance of 47 nanofarads, a working temperature range of -40 to +85 degrees Celsius, a rated voltage of 70 volts, an operating frequency of up to 1MHz and an insulation rating of 0.4 megaohms. Much like other inductors, the S0402-47NF3C is designed to last for an extended period of time with minimal loss in performance and the chip form unit allows for straightforward mounting.

The primary application field of the S0402-47NF3C is in power supplies. The unit is used in switching power supplies to limit the amount of current that can flow from the input side to the output side. Its low inductance rating along with its high frequency and temperature ratings make it ideal for this application. In addition, it is suited to audio-visual equipment, digital signal processing systems, RF communication systems, and Bluetooth electrical devices.

The working principle behind the S0402-47NF3C is based on electromagnetic induction. When electric current is passed through the copper wire winding, it produces a magnetic field that induces the flow of current in the opposite direction. This opposing current opposes the main current flow and reduces the magnitude of the current. This reduces the amount of power required and prevents damage to other components connected in the circuit.

In summary, the S0402-47NF3C is an excellent choice for a variety of space-restrictive applications. It is a specialized component designed to limit the flow of electrical current using electromagnetic induction. It is suitable for use in power supplies, audio-visual equipment, digital signal processing systems, RF communication systems, and Bluetooth devices, primarily due to its low inductance, high temperature, and high frequency ratings. By understanding the construction and working principle of the S0402-47NF3C, engineers can have a better understanding of how the device works and why it is such a valuable option.
