Fixed inductors are electrical components that store electrical energy in the form of a magnetic field. The ER1537-28KP is an example of such a device. It is a surface-mount fixed inductor that has a wide range of applications. The following is an overview of its features, application fields, and working principle.

Features

The ER1537-28KP is a surface-mount fixed inductor with a rated inductance of 28uH ±20%. This device is a high-end model that offers many other features such as low DCR (1.2 mΩ max.) and high saturation current (2A max.). It also has high temperature stability and a wide operating temperature range of -55℃ to +125℃.

Application Fields

The ER1537-28KP is suitable for a wide range of applications. It is designed for high-frequency switching power supplies and voltage regulators. It can also be used in LED lighting, cell phone chargers, computers, and other portable electronics. In addition, it can be used for electronic ballasts, RFID systems, communication systems, and other circuits that require high-frequency switching power.

Working Principle

The ER1537-28KP is an inductor, which works by storing energy in a magnetic field. When an electric current flows through it, a magnetic field is created, which is stored in the inductor as magnetomotive force (mmf). When the current stops flowing, the mmf gradually dissipates and the energy stored in the magnetic field is released. This is what makes inductors valuable in power electronics, as they can be used to smooth out voltage peaks or regulate changes in current.

In addition, the ER1537-28KP has a wide operating temperature range, making it suitable for high-dissipation circuits as well as high-temperature applications. With its low DCR and high saturation current, it can handle high-power applications such as LED lighting. It also benefits from its surface-mount design, making it easy to install and reducing the space it requires in a circuit.

In summary, the ER1537-28KP is a high-performance fixed inductor with a wide range of applications. It offers high-saturation current, low DCR, and a wide operating temperature range. Its features make it suitable for high-power applications such as LED lighting and RFID systems. Furthermore, its surface-mount design makes it easy to install, and its wide range of inductance values makes it a versatile component.
