Fixed Inductors

The S0402-15NH3C is a small, surface-mount fixed inductor that can handle up to 15.0 microhenries. It is a four-terminal device with a coil construction that includes an inductive winding and two terminal pins. This allows it to be connected in a variety of ways, such as series or parallel. The S0402-15NH3C is manufactured using a high quality ferrite material, and is built to meet RoHS and AEC-Q200 standards.

Applications

The S0402-15NH3C is most commonly used in applications such as switching power supplies, general circuit protection, RF circuits, and wireless communications. It can also be used in voltage regulator and other power supply circuits. In RF circuits, the device is used to create inductive filters, while in wireless communications, the device is used to filter out unwanted frequencies. This device is also used in step-down and buck converters, as well as DC-DC converters.

Working Principle

The working principle of a fixed inductor is based on Faraday\'s law of induction. When a changing current passes through a wire, it induces a magnetic field around the wire. This magnetic field is in turn linked to the current, which then creates an opposing force, referred to as back EMF. This back EMF opposes the original current and limits its increase. By increasing the number of turns in the inductor or the amount of current, the back EMF can be increased. This is how the S0402-15NH3C works to protect circuits and filter out unwanted frequencies.

Conclusion

The S0402-15NH3C is a surface-mount fixed inductor that can handle up to 15.0 microhenries. It is a four-terminal device with a coil construction that includes an inductive winding and two terminal pins. It is most commonly used in applications such as switching power supplies, general circuit protection, RF circuits, and wireless communications. Its working principle is based on Faraday\'s law of induction, in which a changing electric current creates a back EMF that opposes the original current and limits its increase. This is how the S0402-15NH3C works to protect circuits and filter out unwanted frequencies.
