Fixed inductors are typically components used in many areas of technology. These components are commonly associated with the electrical, electronics, and other types of technology that require the use of inductors. This article will focus on the 4302-121H application field and working principle, as well as its involvement in the larger category of fixed inductors.

The 4302-121H is a fixed inductor that is often used in many different electronic aspects. Examples of this include switching power supplies, high frequency telecommunication systems, and others. This particular inductor is much larger than typical inductors; the 4302-121H has an inductance of 660mH with a maximum DCR of 4.2 ohms at 25C. The operating temperature for this inductor is also quite low, being rated at -55C to 125C.

Beginning with the application field, this inductor is primarily used in high frequency applications such as switching power supplies. Most of these power supplies tend to use the 4302-121H as they offer high power handling and excellent thermal performance. The inductor is typically sold as a complete assembly, which means that the inductor, power switching MOSFET, and other related components are already included and mounted to the package. This makes assembly easier and faster when compared to other styles of inductors.

When it comes to the working principle of the 4302-121H inductor, the main purpose is to reduce high-frequency noise generated by the power supply. This noise can cause interference in the system or degrade system performance. Additionally, the inductor also serves to reduce the ripple voltage in the output. This ripple voltage is a result of the diode waveform distortion in the rectifier circuit.

The 4302-121H operates in two ways. The primary mode of operation is the linear mode, in which the inductor works to reduce the high-frequency noise. This mode of operation helps to reduce interference and improves system performance. In contrast, the 4302-121H can also be operated in saturable mode. In this mode, the inductor is able to store and release energy. This helps to reduce the output ripple voltage as the stored energy is released in proportion to the current demand.

Overall, the 4302-121H is a fixed inductor that is used primarily in the field of switching power supplies. This inductor works to reduce high-frequency noise and output ripple voltage in the power supply. It is rated at 660mH with a maximum DCR of 4.2 ohms at 25°C and can operate at temperatures of -55°C to 125°C. Finally, the 4302-121H can be operated in both linear and saturable modes for different occasions.
