Introduction of Fixed Inductors
Fixed inductors are electric components that store energy in a magnetic field when electric current is passed through them. Essentially, fixed inductors are formed by wrapping wire around an iron, metal or ferrite core. This wrapped wire coming away from the core creates a loop, or coil, of sorts and is where the magnetic field created by the current is channeled. Commonly, fixed inductors are used in a variety of applications ranging from power supplies, amplifiers, and filtering circuits to telecom and motor control circuits, as well as many other industrial applications.
Applications of SRP4020-1R5M
The SRP4020-1R5M is a fixed inductor that has been specifically designed for applications that require high current. These inductors are highly durable, reliable and feature low oxygen (LO) and tin-plated (T) construction that provide superior resistance to environmental factors and high-power currents. Commonly, a SRP4020-1R5M is used for power supplies, amplifiers, and filtering circuits as well as current limiting, power factor correction and other power electronics applications. Additionally, it can be used as a transformer in audio and automotive applications as well as for a variety of other industrial applications.
Working Principle of SRP4020-1R5M
The SRP4020-1R5M, as is typically with other fixed inductors, stores energy in a magnetic field when electric current is passed through it. This occurs when an electric current is placed in a coil of wire connected to the inductor. The core material of the inductor converts the electrical current into a magnetic field, thus storing the energy in the magnetic field. As the current flows, the inductor’s magnetic field grows, creating more of a loop or coil with the wire and increasing the amount of energy stored. The inductor, therefore, has the ability to store energy even after the current is turned off. Safety Consideration of SRP4020-1R5M
In order to ensure safety, there are certain factors to take into consideration when utilizing the SRP4020-1R5M. The first and most important safety consideration is to acquire one that is specifically designed for the highest current capacity possible, as too low of a current rating may cause catastrophic failure. Additionally, the inductor should be properly insulated, and any capacitive components it is paired with should match the inductor’s current rating to prevent over-powering it. Finally, the inductor should be placed in a location where it won’t be easily exposed to environmental stresses or mechanical vibration- producing equipment, such as fans, compressors, loose connections, and other electrical components. The location should also be far enough away from any high voltage sources that may be present. By considering these safety factors when using the SRP4020-1R5M, one can minimize the chances of failure and ensure optimal performance.
