Fixed inductors, or inductors that are designed to have a fixed inductance value, have a wide range of applications. One particular common type is the S0402-4N7F3S inductor. This type of inductor is used in many different electrical and electronic devices, from consumer electronics to industrial applications. It is a compact, low-profile surface-mount device (SMD).

The S0402-4N7F3S inductor is a four-terminal, rectangular shaped, non-polarized component. It has a footprint of 0.042 in x 0.024 in, with an overall height of 0.023 in. It is made with a ceramic core material and a dielectric layer. The inductance value of this component ranges from 4.7µH to 27.8µH, with an operating temperature of -55°C to 125°C. It is classified as AEC-325 part number OCR3622 (or OCR3623). Its application fields include DC/DC converters, DC/AC inverters, power line filters, circuit protection devices, switching regulators, instrumentation amplifiers, audio circuits, and timing applications.

The basic working principle of this inductor involves the creation of a magnetic field in response to a current applied to it. This magnetic field then induces a voltage in the opposite direction, according to Faraday’s law of induction. This voltage, called an inductance voltage, is proportional to the rate of change of current. This current change creates a magnetic flux, which is also called a magnetic field. The generated inductance voltage opposes the change in the current, thus resulting in a stored energy in the form of the inductance energy.

In addition to the above features, S0402-4N7F3S inductors can be found in a variety of package sizes and shapes. This helps them fit into tight places in electronics, where space is at a premium. These materials are also resistant to shock and vibration, which makes them ideal for use in heavy-duty applications. In order to ensure the reliability of the part and to reduce noise both in DC and AC operating conditions, this type of inductor should be subjected to stringent testing procedures.

The S0402-4N7F3S inductor is a versatile component that is used in many different types of applications. Its features make it well suited for a variety of electronic circuits. It is relatively small in size, which makes it ideal for miniaturizing the circuits. The varying inductance values combined with the low-profile design allow for the inductor to be used in a variety of different operating conditions. The design is also reliable and can withstand heavy-duty conditions, making it highly applicable in many different industrial and consumer-based applications.
