Fixed inductors are components used in electronic circuits for their inductance. These components, also known as chokes, have different types, including 4302-681H. The 4302-681H inductor has quite a few features and application fields, and its working principle will also be discussed.

Characteristics and Application Fields

The 4302-681H is an axial leaded choke that has some special characteristics. For instance, it has a 10 ohm, 265 H inductance, and a 75 mA DC rated current. Moreover, it has an incredibly low height and it is encased in an enameled copper wire thats nickel-plated. These features make it ideal for various application fields.

This type of inductor can be used to build all sorts of devices, such as inverters, motor drives, solar inverters, HVAC systems, and medical equipment. Additionally, its shielded construction makes it suitable for reducing unwanted interference with sensitive electronic circuits, and for preventing the spread of noise from the single-ended circuit.

Working Principle

The 4302-681H produces electromagnetic fields when current is applied to it. In an inductor, when a current flows through a winding, a magnetic field is produced and concentrated in the windings and ferrite core. When this magnetic field is changing, a voltage is induced that is equal to the number of turns times the rate of change of the magnetic flux. This voltage drop or rise in the inductor opposes the change of the current that caused it, resulting in a "back-EMF," blocking some of the current from passing through the inductor.

When the current is steady, the inductor just passes it without any resistance. Furthermore, since the size and shapes of ferrite cores affect its inductance, by changing the core or the size of the winding, the inductance for the 4302-681H can be fine-tuned accordingly.

Conclusion

The 4302-681H fixed inductor has many features and application fields. It is designed for use in motor drives, inverters, solar inverters, HVAC systems, and medical equipment, and its shielded construction makes it effective in noise reduction. Moreover, its inductance can be adjusted, giving it more flexibility. All these features make this type of inductor an ideal choice in a wide range of applications.
