Fixed Inductors

Inductors are electrical components used to oppose changes in electric current. Fixed inductors are used in electronics to provide a consistent electrical current. 4307R-685K is one of the most popular types of fixed inductors for a variety of applications.

4307R-685K Application Field

The 4307R-685K is primarily used in high-frequency switching applications. Its high current capability and incredibly low DCR provides efficient energy transfer, making it great for use in DC-DC converters. It is also frequently used in communications, power control and circuit protection applications.The 4307R-685K can be used in a wide range of operating temperatures and is capable of handling high temperature conditions. This makes it ideal for use in high-power applications where extreme heat is common. It is also corrosion-resistant and features excellent RF shielding, making it suitable for use in high-energy fields.

4307R-685K Working Principle

The 4307R-685K is a fixed-value inductor, meaning that its inductance does not vary with frequency or temperature. This gives it unique advantages over other types of inductors, such as variable inductors. The 4307R-685K works by resisting changes in electric current. When a current is introduced to the inductor, an electromagnetic field is created which opposes the current. This is known as inductance and is measured in Henrys (the unit of inductance).The 4307R-685K also features ferrite core technology, which provides a higher inductance than traditional thin-film inductors while consuming less power. This technology also enables it to operate at high temperatures, and reduces its sensitivity to noise.

Conclusion

The 4307R-685K is a popular choice for high-frequency switching applications due to its high current capability and low DCR. Its ferrite core technology enables it to operate efficiently at high temperatures and with reduced noise sensitivity. It is also widely used in communications, power control and circuit protection applications.
