Fixed InductorsFixed inductors are devices designed to provide a steady electric current flow between two electrical connections. They are used in a variety of applications ranging from power supplies in computers and consumer electronics to motors and control systems. The S0402-8N2H2S is a surface mount, molded, fixed inductor produced by Susumu Co. and is designed to meet high temperature requirements when used in high reliability applications.This particular inductor is a unidirectional, ceramic core unit that can be operated at a temperature range of -55°C to +125°C. At this temperature range, Susumu Co. guarantees that the line impedance will be within 0.4 mΩ and the line inductance value will be within 0.3 µH to 7.2 µH. The capacity of the S0402-8N2H2S varies depending on the inductance, ranging from 0.1 µF to 10 µF.In terms of its application field, the S0402-8N2H2S is ideal for use in switching power supplies, battery chargers, and power amplifiers. It is also well-suited to applications where space is limited, such as in mobile phones, laptops and other confined spaces. It is also normally used in consumer, medical, and industrial turbines, as well as in the automotive industry.The working principle of the S0402-8N2H2S is based on Faraday\'s law of induction, which states that a changing magnetic field will induce an electric current. In the case of this particular inductor, a steady electric current is fed into the coil, and the magnetic field generated by the current induces a voltage across the coil, which opposes the current. This self-induced voltage, or back electromotive force, creates a counter-current in the coil, which is equal and opposite to the applied current, resulting in a reduction in the flow of current. This is known as inductive reactance.The S0402-8N2H2S also has a self-resonant frequency (SRF), which is the frequency at which the inductance and capacitance of the unit are inversely proportional and in phase with one another. This creates a resonance within the unit, which can be utilized to reduce the frequency-dependent impedance of the unit. This is useful in applications where high power frequencies are required.In summary, the S0402-8N2H2S is a unidirectional, surface mount, and molded fixed inductor designed to meet high temperature requirements when used in high-reliability applications. It has a temperature range of -55˚C to +125˚C, a line impedance of 0.4 mΩ, and a line inductance of 0.3 µH to 7.2 µH. It is suitable for use in switching power supplies, battery chargers, power amplifiers, mobile phones, laptops, consumer appliances, electrical turbines, and the automotive industry. Its working principle is based on Faraday’s law of induction and it has an SRF that can be utilized to reduce the frequency-dependent impedance of the unit.
