Fixed Inductors

An inductor, also called a coil, choke or reactor, is an electrical component which stores energy in a magnetic field when a current flows through it. Fixed inductors refer to components which have a fixed inductance and are designed and used for a specific purpose. One such inductor is the SDR1005-470K.

SDR1005-470K Application Field

The SDR1005-470K is a shielding type fixed inductor used in electrical noise suppressing filters. This type of inductor is used specifically for suppressing high-frequency noise, such as noise generated by switching power supplies or TVs. The SDR1005-470K is able to suppress high-frequency noise at frequencies over 1MHz, making it a useful tool for such applications.

SDR1005-470K Working Principle

The SDR1005-470K is made up of a core and a wire wound around it. When a current passes through the wire, it generates a magnetic field inside and around the core. This magnetic field stores energy in the form of induced voltage. The amount of energy stored is proportional to the current passing through the inductor and it increases as the current increases. As a result, the inductance of the inductor will increase. This magnetic field is used to suppress the high-frequency noise generated by switching power supplies or TVs, so that the intended electrical signal remains less distorted. It is also used for impedance matching and power filtering.

Conclusion

The SDR1005-470K shielding type fixed inductor is designed for suppressing high-frequency noise. It can be used in various applications where this type of noise needs to be suppressed, such as switching power supplies or TVs. The working principle of the inductor is based on the generation of a magnetic field when a current is passed through it, and the storing of energy in the form of induced voltage in the magnetic field, proportional to the current. With its features and capabilities, the SDR1005-470K is quickly becoming a popular choice for noise suppression needs.
