Fixed inductors refer to the inductors which are made of multiple core coils or air cores with fixed inductance and fixed windings. ELJ-PA680KF2 is one type of fixed inductor which can be widely used in various electrical applications. In this article, we will discuss the application field and working principle of ELJ-PA680KF2.

ELJ-PA680KF2 is suitable for high-frequency circuits, such as switching power supply circuits, amplifier circuits, and communication circuits. Its superior characteristics make it can significantly reduce the size and weight of the overall device. The high saturation current of the inductors can reduce the volume of the switching power converters and reduce the energy loss caused by the coil. The inductor\'s low DCR and high surge current capability can provide sufficient energy transfer for high-efficiency circuits and effectively reduce the number of mistakes caused by short circuit of EMI.

ELJ-PA680KF2 consists of a winding composed of multiple coils of insulated wire wound around a magnetic core. This core can be made of ferrite, mu-metal or other materials. The inductance of the winding is related to the inductance of the core material and the number of winding turns. When an AC current is passed through the winding, the magnetic field will be generated in the core. The strength of this magnetic field is directly proportional to the magnitude of the current. The generated field links the winding and induces a voltage that opposes the applied voltage. This opposing voltage is called self-induced voltage or counter electromotive force and is determined by the value of inductance and the amount of current.

The ELJ-PA680KF2 fixed inductor uses a special winding technology that helps to reduce the DC resistance of the inductors. This means that the power loss generated when the current passes through the inductors is reduced, and the device can maintain a high working efficiency for a longer period of time. The winding of the inductor is also made of two layers of insulation that improves the heat dissipation of the device and makes it possible to reduce the operating temperature of the device.

ELJ-PA680KF2 has a wide range of applications, such as in switching power supplies, converter circuits, DC-DC converters, and high-frequency amplifiers. The device\'s low DCR and high surge current capability make it suitable for applications demanding excellent energy transfer and heat dissipation. The product\'s low operating temperature, low power loss, and high efficiency make it an industry-leading fixed inductor.

In summary, ELJ-PA680KF2 is a type of fixed inductor that has a wide range of applications. Its high saturation current, low DCR, and high surge current capability make it an ideal choice for high-performance applications. The winding of the inductor is made of two layers of insulation that helps to improve the heat dissipation of the device. This makes ELJ-PA680KF2 a great choice for applications demanding reliable performance and high efficiency.
