Fixed Inductors

Fixed inductors are devices that store electrical energy in the form of a magnetic field. They work by passing current through a conductor and the resulting magnetic field is stored in an inductor, which is represented by a symbol. An inductor\'s worth is measured in henries, which is the unit of measure for inductance. The higher the number of henries, the greater the inductance of the inductor. The 1945-21J fixed inductors are designed to offer high power-handling capability, suitable for all types of switching power supplies. It has a total inductance of 45 to 65 millihenries and maximum AC current of 35 amperes. The 1945-21J series are constructed with high quality materials that ensure high reliability over a wide temperature range. It is an ideal product for various power supply and filter applications. The working principle of a fixed inductor is based on Faraday’s Law of induction, which states that a changing magnetic flux induces a voltage in a conductor. In an inductor, the changing current creates a changing magnetic field that generates an induced voltage in the inductor\'s coil. This induced voltage is proportional to the rate of change of the current. This principle is also known as Lenz\'s Law, as it states that the induced electromotive force (EMF) has the same direction as the current, thus opposing the change in the current. In terms of usage for 1945-21J, it has been used in applications such as high frequency filter inductors, switching power supplies, audio amplifiers, RF matching networks, and electronic ballasts. This inductor is suitable in applications that require high current with low losses that need to be filtered. In addition, the 1945-21J also has high power-handling capabilities, making it ideal for high-power filtering systems and high temperature environments. It is also a great choice for applications that require high jitter due to its low EMI interference. Overall, the 1945-21J fixed inductors are devices with high power-handling capabilities, low losses, and high jitter. It can be used in a variety of applications that require high current filtering, including those in high temperature environments. The working principle of the 1945-21J is based on Faraday’s Law of induction and its frequency response creates a low EMI interference. With its features, the 1945-21J fixed inductors are a great choice for a variety of applications.
