Fixed inductors are passive electrical components with a wide range of applications in the power and signal industries. The most common type, the S0402-3N3F3C, is an SMD ceramic chip inductor with a wirewound construction and a rated inductance of 3.3nH. It has a rated current of 15mA, a voltage rating of 125V, and a tolerance of ±20%. This inductor is used in power and signal circuits where stability and accuracy are essential.S0402-3N3F3C fixed inductors are widely used in various applications, such as AC/DC power supplies, switched mode power supplies, DC/DC converters, DC/AC inverters, battery chargers, switching regulators, stress test equipment, mobile phones, LED lighting systems, and other electronic equipment. The working principle of the S0402-3N3F3C fixed inductor is based on Faraday\'s law of electromagnetic induction. Faraday\'s law states that a changing magnetic field induces an electromotive force or EMF in a conductor. When an alternating current flows through the inductor, a magnetic field is generated in the coil, inducing an EMF. This EMF opposes the motion of electrons in the coil, producing an inductive reactance. This reactance limits the flow of current, maintaining a constant level of current in the circuit.The S0402-3N3F3C inductor is also designed with an internal protection circuit to prevent overcurrent and overvoltage. This circuit includes protective resistors, bidirectional diac blocking diodes, and transient suppressor diodes. The diode array helps to reduce voltage transient peaks, and the protective resistors help to limit the inrush currents. In addition, this inductor is constructed with a self-extinguishing thermal fuse for overload and short-circuit protection.The S0402-3N3F3C fixed inductor is a vital component in power and signal circuits. It is reliable, durable, and has a wide range of application fields. With its protection circuit, this inductor can withstand high temperatures and heavy currents, ensuring circuit stability and reliable operation in the long run.
