Fixed Inductors

Fixed inductors, also known as chokes, are devices used to store electrical energy in the form of a magnetic field. They are used in a wide variety of applications to filter out noise in power or data transmission lines and to suppress high-frequency interference from entering or leaving a device. Fixed inductors provide mitigation of radio frequency interference (RFI) into filters. The SDR0906-821KL fixed inductor is a great example of how modern electrical components can be used to efficiently store energy in the form of a magnetic field.

The SDR0906-821KL fixed inductor is a highly stable SMD power inductor designed for use in noisy, high-amplitude and low-DC resistance applications. The SDR0906-821KL fixed inductor is constructed using a molded inductor core composed of ferrite and a secondary coil of wire. It features excellent high-frequency performance, high-current handling capacity, and low DC resistance. This inductor can withstand high-frequency noise up to 5GHz and has an operating temperature range of -40°C to 85°C. It is also RoHS compliant and has a UL 94V-0 flame rating.

The working principle of a fixed inductor is based on the principle of electromagnetic induction, which states that a changing magnetic field creates an electric current in a wire. When an inductor is connected to a power source, a varying current flows in the coil and creates a magnetic field around it. This magnetic field restricts the current flow, thereby restricting the voltage drop across it. As a result, a fixed inductor functions as an electrical filter and limits the transfer of electrical noise.

The SDR0906-821KL fixed inductor is typically used in applications such as DC/DC converters, buck converters, switching regulators, low dropout regulators, laptop power supplies, multi-stage noise filters, and more. Additionally, it can be used in other applications where a low DC resistance and high current handling capability are required.

Conclusion

Fixed inductors are extremely useful components which can be employed in numerous applications to reduce noise and EMI. The SDR0906-821KL fixed inductor is a great example of a modern component which uses the principle of electromagnetic induction to store energy in the form of a magnetic field and provide excellent high-frequency performance. It can be used in applications such as DC/DC converters, buck converters, switching regulators, and more, making it a great option for reducing electrical noise.
