Fixed inductors are passive electrical components designed to store energy in the form of an electromagnet field. The L-15W15NJV4E is a type of fixed inductor that is used in a range of different applications, including power supplies, switched-mode power supplies, RF applications, and signal filtering. It is a small, high efficiency component with a low profile that is ideal for use in densely populated printed circuit boards (PCBs). In this article, we will look at the application field and working principle of the L-15W15NJV4E.

Application Field

The L-15W15NJV4E is designed for use in applications where high efficiency and low profile are required. Its small size makes it ideal for densely populated PCBs, and its low profile means it can fit into tight spaces. It is suitable for use in power supplies, switched mode power supplies, RF applications, and signal filtering.

In power supplies, it is used to filter out DC ripple, allowing the power supply to operate with greater efficiency and stability. It is also used to help prevent frequency instability and transients, ensuring that the power supply operates at the desired frequency. Similarly, in switched mode power supplies, it is used to filter out noise and reduce switching losses, while also helping to minimize electromagnetic interference (EMI).

In RF applications, the inductor is used to create a tank circuit, allowing signals to be filtered and attenuated. It is also used in signal filtering to reduce noise, helping to improve signal integrity. Finally, in signal filtering, the L-15W15NJV4E can also be used to reduce input capacitance and improve input impedance matching.

Working Principle

The L-15W15NJV4E is an inductor, meaning that it uses inductance to store energy in the form of an electromagnetic field. This energy is generated when a current passes through a coil of wire, creating a magnetic field. This magnetic field then induces a voltage in the same coil, which in turn causes a current to flow in a second coil, creating a back-EMF. This back-EMF then is dissipated in the form of heat.

The inductance of the L-15W15NJV4E is approximately 15uH. This means that for a given applied voltage, it will store a specific amount of energy. This makes it ideal for use in power supplies and switched mode power supplies, where it can be used to filter out noise and reduce switching losses. Similarly, in RF applications, it can be used to create a tank circuit, allowing signals to be properly filtered and attenuated.

The power rating of the L-15W15NJV4E is 15 watts, and it can operate at temperatures up to 125°C. This makes it suitable for use in high-temperature environments, such as inside power supplies and switched mode power supplies. It also has a low profile, making it ideal for use in densely populated PCBs.

In conclusion, the L-15W15NJV4E is a small, high efficiency fixed inductor that can be used in a variety of different applications. It is suitable for use in power supplies, switched mode power supplies, RF applications and signal filtering, and it can operate at temperatures up to 125°C. It also has a low profile, making it ideal for use in densely populated PCBs. With its ability to filter out noise and reduce switching losses, the L-15W15NJV4E is an excellent choice for a range of different applications.
