Fixed Inductors

Inductors, also called coils or chokes, are passive electronic components that store energy in a magnetic field when electric current is flowing through them. Fixed inductors have a fixed inductance value, meaning the inductance is not adjustable. One example of a fixed inductor is the 4302-331F.

The 4302-331F inductor is a small, surface-mounting device designed for use in high-frequency switching and filtering circuits. It is rated for a maximum current of 0.2A and a maximum operating temperature of 125°C, allowing it to be used in a variety of applications. It is made from a ferrite core and uses copper wire for the winding material. The inductance value of the 4302-331F can range from 0.33uH to 33uH, depending on the application.

The 4302-331F is typically used in switching power supplies, DC-DC converters and charge pump circuits. These types of circuits require low-level inductance values in order to reduce noise and minimize electromagnetic interference. The 4302-331F can also be used in power line filters, electronic ballasts, and choke coils. It is also used in the automotive, medical, and communications industries.

The working principle of a fixed inductor like the 4302-331F is based on the generation of energy from a changing magnetic field. When electric current flows through the inductor windings, a magnetic field is created around the device. As the current increases, the magnetic field strength increases, causing the energy stored within the inductor to increase until it reaches a peak level. When the current is reduced or stopped, the energy is then released back into the circuit.

In summary, the 4302-331F is a surface-mounting fixed inductor. It operates on the principle of energy stored in a magnetic field generated by a passing electric current. The inductance value can range from 0.33uH to 33uH, depending on the application. Common applications for the 4302-331F include power supplies, DC-DC converters, charge pumps, power line filters, electronic ballasts, and choke coils. It can also be used in the automotive, medical, and communications industries.
