Fixed Inductors
Fixed inductors, also known as chokes, are components of electrical circuits used for storing energy in a magnetic field and for blocking or regulating AC voltages. The ER1641-154KR is a high performance fixed inductor manufactured by Erpromet, designed to improve system performance and reduce EMI interference.Working Principle
Fixed inductors work on the principle that when a wire is wound around a core of material, a magnetic field is created which will oppose any changes in current. When a current flows through the winding of the inductor, the resulting magnetic field stores energy with the strength of the field increasing with the amount of current. When the current is stopped, the energy stored in the magnetic field is released.The ER1641-154KR fixed inductor is a high power device designed to provide efficient filtering and immunity from EMI interference. It has an air cored, flat shielded construction that minimizes component size and reduces series inductance. The inductor has low DC resistance, allowing it to handle large currents, and the flat coil structure ensures a low height profile, making it ideal for space-constrained applications. The inductor also has a high saturation current, meaning it can handle high DC currents with minimal distortion and losses.Fixed inductors can also be used to regulate voltage. When a varying voltage is applied to the inductor, the change in the current through the inductor will be opposition to the voltage change, creating a voltage regulator. The ER1641-154KR has an improved power rating allowing it to provide better voltage regulation in applications where high current is present.Application Fields
The ER1641-154KR fixed inductor is designed for use in a wide range of applications including switch-Mode power supplies, DC-DC converters, multiple voltage systems, automotive applications, home appliances, charging systems, and telecommunications. Leakage currents caused by EMI radiation can be a problem in some of these applications, and the ER1641-154KR provides filtering and shielding to reduce interference. The low height profile also makes the component well suited for portable devices where space is a premium.In addition to reducing noise and leakage currents, the inductor can also be used for energy storage. This is useful in applications such as DC-DC converters, where the inductor can store energy as it is converted from AC to DC and then released when required. This helps to ensure that the output voltage remains stable and that all components are operated efficiently.The ER1641-154KR fixed inductor is a component that can be used in a variety of applications for increased performance and improved EMI immunity. It has a high power rating, making it suitable for applications requiring high current and efficient filtering, as well as energy storage and voltage regulation. The small size and flat coil profile make it ideal for space-constrained applications, while its air cored construction helps to reduce distortion and linearity issues.The specific data is subject to PDF, and the above content is for reference
