Fixed inductors are electrical components that store energy in a magnetic field created by a coil or slab of wire. These are some of the most commonly used components in electronic circuits, and the 4302-273F is a type of inductor from a popular series by Coilcraft. This article will explain the application field and working principle of 4302-273F consisting of molded power inductors which are designed for general-purpose power supply noise suppression, high current power supply filter, and power supply ripple smoothing.

Applications

The 4302-273F Series of molded power inductors is applicable to high frequency applications. With low resistance and high saturation current ratings, these inductors are suitable to be used in consumer electronics, communications, automotive and industrial applications. It is ideal for noise suppression in strong interference areas, high current applications and for power supply ripple smoothing. It can provide effective filtering performance from 1MHz to 10MHz frequency range. Some common application examples of the 4302-273F are DC/DC converters, LED lighting, audio amplifiers, battery chargers, etc.

Working Principle

An inductor is a combined electrical and magnetic component. It is composed of a coil of wire, metal core and a magnetic material, and the core increases the inductance of an inductor. It can be represented as a helix coil, which creates a balancing magnetic field within itself. The 4302-273F becomes an inductor when current flows through its winding. Due to the presence of metal core and magnetic materials, the 4302-273F has a higher Inductance rating.

When current flows through the inductor, a magnetic field is created around the coil. The magnitude of the field is directly proportional to the magnitude of the current. This magnetic field induces a self-induced EMF that opposes the incoming voltage. As the current increases, the back EMF generated by the inductor also increases, which limits the current. The inductance will drop once the inductor is saturated. Therefore, the 4302-273F can effectively limit the voltage and prevent large currents from flowing through its winding.

In addition, 4302-273F also serves as a low-pass filter. This filter suppresses high-frequency noise and ripples in the voltage, providing clean and steady currents for electronic devices. It can be used for power supply filtering and high current applications.

Conclusion

The 4302-273F is a molded power inductor designed for general-purpose noise suppression, high current applications, and power supply ripple smoothing. It can provide effective filtering performance from 1MHz to 10MHz frequency range and is commonly used in consumer electronics, communications, automotive and industrial applications. The working principle of 4302-273F is to create a force opposing the incoming voltage when current flows through its winding, as well as for power supply filtering.
