Fixed inductors have a variety of applications, from providing optimal electrical current to damping electrical signals so they adhere to specified values or waveforms in radio and communications systems. SDR0603-470KL is one type of fixed inductors with high reliability. In this article, the application field and working principle of the SDR0603-470KL will be discussed.

Application Field

The SDR0603-470KL is a 4.7uH 100mA ferrite core inductor that is typically employed to suppress EMI/RFI noise in switching power converter applications. It offers excellent solderability, heatshrink insulation and, due to its strong non-linear magnetic force, very low B leakage. It also features a self-shielding package, offering excellent ground performance. With its saturated core, the SDR0603-470KL can reduce the inrush current in circuits. It is highly suitable for DC-DC converters, air conditioning systems and other LED lighting products.

Working Principle

When electricity passes through an inductor, a magnetic field is generated around the inductor. This magnetic field will oppose any change in the electric current that passes through the inductor. This opposition to change is called inductance. The magnitude of the inductance of the SDR0603-470KL is 4.7uH. The core material of the SDR0603-470KL is ferrite which allows energy to be efficiently stored in a relatively small form. The high permeability of ferrite increases the number of magnetic lines in the core, making the inductor more efficient.

The SDR0603-470KL inductor can also be used to reduce noise when buffering AC signals, such as AC motors. The inductor helps to smooth out the AC signal, preventing switching components from ringing due to switching currents. With its high tin-soldering temperature tolerance and high-temperature resistance, the SDR0603-470KL can be used in high temperature environments.

Conclusion

The SDR0603-470KL is a 4.7uH 100mA ferrite core inductor which is highly suitable for DC-DC converters, air conditioning systems, LED lighting products, and other applications. Due to its high permeability, the SDR0603-470KL can provide excellent efficiency and reduce inrush currents in circuits. It also has high tin-soldering temperature tolerance and high-temperature resistance, making it ideal for high-temperature environments. With its versatile features and applications, the SDR0603-470KL is an excellent fixed inductor choice.
