ER1025-24KR Inductors, Coils, Chokes

Fixed inductors are electronic components that store energy magnetically in a winding of wire called coils. The term is commonly used to identify components in which the inductance of the coil remains approximately constant with changes in applied frequency or current. The most common arrangement of a fixed inductor is the air-core coil, which consists of a coil of insulated wire wound on a cylindrical form, without any ferromagnetic core material. Fixed inductors can also be constructed with cores made of a ferromagnetic material like iron, steel or ferrite.

ER1025-24KR is one type of air-core fixed inductor with radial leads. Its lead spacing is 10 mm. The inductance of a coil changes with the rate of current through it, and this type of fixed inductor has a tolerance range from±20 to±30%. This fixed inductor can be used in frequency division, signal transmission, and AC/DC current conversion lines, and so on.

The ER1025-24KR fixed inductor uses the principle of Faraday’s law which states that the inductor stores energy in a magnetic field whenever a current passes through the inductor. Whenever the current changes, the magnetic field also changes and the inductor acts like a transformer, dissipating or absorbing electrical energy to or from the surrounding environment. The more turns of wire on the inductor, the higher the inductance. The inductance of an air-core inductor is also affected by the size and shape of the inductor.

ER1025-24KR used material with high saturation magnetic induction intensity, which could offer high permeability to it, so that it could reduce the power loss in the inductance. This type of inductor also has a good ability of heat radiation. The temperature rise of the substrate is within the permissible range.

In conclusion, the ER1025-24KR fixed inductor is designed for applications such as frequency division, signal transmission, and AC/DC current conversion lines, and has the advantages of high permeability, low power losses, and good heat radiation. As such, it is a highly suitable choice for engineers looking for reliable electronic components.
