IntroductionFixed inductors are electronic components that store and release electrical energy in the form of magnetic energy. They are used in many different types of electronic circuits including power supplies, switching supplies, amplifiers and RF circuits. One type of fixed inductor is the 2100HT-391-V, which is used in a wide range of applications and is well-suited for use in commercial, industrial and military applications. This paper will discuss the application field and working principle of the 2100HT-391-V fixed inductor. Application Field of the 2100HT-391-VThe 2100HT-391-V fixed inductor is a small and compact component made from a ceramic core and is often used in SMPS (Switch-Mode Power Supply) converters. It is designed to provide a wide range of inductance values, from 0.56 uH to 1.2 uH, and can handle up to 1.2A. It is also designed to have a low resistance (ESR) of 0.69Ω at 25°C, which makes it suitable for high frequency applications.The 2100HT-391-V is used in power supplies, DC/DC converters, audio amplifiers, motor control circuits, telecommunications equipment and other high-frequency circuits. It is also widely used in other applications such as LED displays, security systems and automotive electronics. It is particularly well-suited for use in military applications due to its high performance and ruggedness.Working Principle of the 2100HT-391-VThe 2100HT-391-V fixed inductor operates on the principle of inductance. Inductance is the property of an electrically conducting material through which a changing magnetic field creates an electromotive force (EMF). The 2100HT-391-V consists of a coil of insulated wire wrapped around a ceramic core. When current flows through the coil, the magnetic field generated by the coil generates an EMF that opposes the flow of the current. This creates a back EMF that maintains a constant current.The 2100HT-391-V also has a self-resonant frequency that is the frequency at which the inductance of the coil is equal to its capacitance. This frequency is what allows the inductor to operate at high frequencies without the need for an external capacitor. The self-resonant frequency also creates a high impedance at frequencies above the self-resonant frequency, which helps to suppress noise and interference from other parts of the circuit.ConclusionThe 2100HT-391-V fixed inductor is a compact and reliable component that is widely used in a variety of applications. It operates on the principle of inductance and has a self-resonant frequency that makes it suitable for high frequency applications. It can handle up to 1.2A of current and has a low resistance (ESR) of 0.69Ω at 25°C, which makes it well-suited for use in military applications.
