Fixed InductorsFixed inductors are inductors with a fixed inductance value designed to operate at a specified frequency. They are commonly used in electronic circuits as passive components for powering applications with inductive loads. The SDR2207-680KL is a fixed inductor from Sumida Corporation. It is designed for use in power supply applications such as power converters, Class D high-efficiency audio amplifiers, and LED lighting systems.Working PrincipleThe working principle of the SDR2207-680KL is based on Faraday’s law of induction. When the current in the circuit changes, it produces a magnetic field around it. This magnetic field induces an electromotive force (EMF) in the opposite direction. This EMF counteracts the change in current, making the inductor have a fixed inductance. For a fixed inductor, its inductance is determined by its physical geometry and the permeability of the core material. The SDR2207-680KL\'s very low profile and high current capability make it ideal for use in space-constrained applications such as cell phones, computers, and TVs. It is constructed using high-permeability core material and a shield, so that the conductor path minimizes noise and crosstalk. It also features a high insulation resistance and can withstand high temperatures. Application FieldDue to its high current capability and low profile, the SDR2207-680KL is suitable for use in a variety of power supply applications. It can be used in high-power Class D audio amplifiers to provide high-current and low-noise operation. It is also suitable for use in LED lighting systems,where it can be used to convert a DC power source into a sinusoidal AC waveform. In addition, it can be used in battery chargers and power converters to convert high-voltage AC power sources into low-voltage DC power sources. The SDR2207-680KL is also suitable for use in switching voltage regulators, where it can help reduce the self-inductance and noise produced in the switching process. It is also suitable for use in applications that involve fast switching and high-speed signal transmission.ConclusionThe SDR2207-680KL is a fixed inductor from Sumida Corporation. Its high current capability and low profile make it ideal for use in space-constrained applications, such as cell phones, computers, and TVs. It is suitable for use in a variety of power supply applications, such as high-power Class D audio amplifiers, LED lighting systems, battery chargers, power converters, and switching voltage regulators.
