Introduction To Fixed Inductors

A fixed inductor, also known as a choke or coil, is an electrical device used to store energy in a magnetic field. Generally, the storing of energy in the magnetic field is accomplished by constructing an inductor with a winding of insulated copper wire. When subject to an electrical current, a fixed inductor sets up a magnetic field around the wire windings which store energy. When the current flow to the inductor is stopped, the energy stored in the magnetic field is released. As such, a fixed inductor can be used to refine DC and AC currents by providing a degree of resistance to changes in current and maintaining a constant electric charge.

ER1025-00KS Application Field and Working Principle

The ER1025-00KS is a fixed inductor manufactured by Sunlord Co., Ltd. Its application field includes cellular phones and other portable electronic products as well as high-end audio products. The particularity of this model is that it allows for very high efficiency, small size and small DC resistance. With its operating temperature range from -40℃ to 85℃, it is suitable for a wide range of environments.The ER1025-00KS is a type of leaded fixed inductor, which basic structure consists of a core, a winding, a metallic shell, a winding cover and a solderable lead. It uses an etched inductor core and has a DC resistance of 0.08 Ohm. Its rated inductance is 10 uH, and its rated current is 2.0 A. The working principle of the ER1025-00KS is based on Faraday\'s law of induction. This law states that a changing magnetic field within an inductor will induce a current in it. This current creates a magnetic field around the inductor. As the current continues to drop, the magnetic field produced by the inductor will begin to decay, which causes the energy stored in the magnetic field to be released back into the circuit. This process helps to maintain the current flow and prevents undesired fluctuations. In addition, the solar resistance of the ER1025-00KS is minimal, which ensures minimal power losses when the circuit is operating. This feature helps to maintain greater efficiency and less electromagnetic interference.

Conclusion

The ER1025-00KS is a type of fixed inductor designed for use in a variety of electronic products. Its use of an etched inductor core and minimal solar resistance help to ensure efficient operation with minimal power losses and electromagnetic interference. The ER1025-00KS is a suitable choice for applications that require efficient storage of energy in a magnetic field.
