Fixed inductors are components used to store electrical energy in the form of magnetically stored energy. This article will be discussing the application field and working principle of PA2891.321HLT.

PA2891.321HLT is a fixed inductor specifically designed for high frequency applications. Its construction consists of a cylindrical ferrite core and two copper wire coils. The inductor is soldered directly to the PCB.

The size of the inductor can vary depending on the desired outcome and the application field. The larger the inductance, the higher the cost and power rating, and vice versa.

The primary application field for PA2891.321HLT is in applications requiring high frequencies and low inductance, such as switch mode supplies, role based communication systems, and wireless power supplies. Due to its low inductance and small size, it is also becoming increasingly popular for use in Bluetooth, Wifi, and Zigbee applications.

When it comes to the working principle of PA2891.321HLT, the core principle is that the inductor works by generating a magnetic field. This magnetic field is generated by passing current through the two coils. The magnitude of the magnetic field generated depends on the amount of current passing through the coils, as well as the amount of wire area within the coils.

Within the magnetic field generated, the copper wire coils act as conduits for electromagnetic energy, which causes the inductor to induce a voltage across its terminals. The induced voltage will be proportional to the rate of change of the magnetic field and the number of turns in the coil.

As the current through the coils continues to increase, the induced voltage will also increase. This allows the inductor to act as a reactive component, as it is able to store and release electrical energy. As the current decreases, the induced voltage will also decrease, allowing the inductor to release the stored energy.

When selecting a PA2891.321HLT fixed inductor, it is important to pay attention to the correct ratings. For example, the power rating of the inductor needs to be higher than the expected power needs of the application, as the inductor can become quickly become damaged if it is too low. Additionally, the size of the inductor needs to be considered, as too small a size can lead to increased losses and heat generation.

In summary, PA2891.321HLT is a fixed inductor designed for high frequency applications. It is constructed with two copper wire coils and a ferrite core, and is soldered to the PCB. Its primary application fields are high frequency applications such as switch mode power supplies, role based communication systems, and wireless power supplies. The working principle of the inductor is that it generates a magnetic field as the current passing through the two coils increase, leading to an induced voltage across the terminals. When selecting a PA2891.321HLT fixed inductor, the size of the inductor and the power rating of the inductor need to be taken into consideration in order to ensure that the inductor meets the needs of the application.
