Fixed inductors, also known as chokes, are passive inductor components typically composed of insulated wire coiled around a ferrite core material. When connected to a direct or alternating current source, the inductor stores energy in its magnetic field and can be used to filter out certain frequencies or reduce voltage from a single source to multiple loads. The 2500R-74F is a fixed inductor designed for very low power applications, such as headphone lines, low-voltage regulated power supplies, and antenna drives. It has a relatively low DC resistance of 0.3 milliohms, and can withstand up to 1.2 amps of current. It has an inductance of 74 microhenries, a primary flow current of 0.12A, and an leakage inductance of 0.25 microhenries.The 2500R-74F operates through the electromagnetic principles: when a current carrying wire is wound into a coil, it creates a magnetic field. This magnetic field can be used to induce a voltage in an electric circuit. As the current in the primary coil is changed, the amount of induced voltage in the secondary coil will also change. The 2500R-74F utilizes this principle by using an undulating magnetic field created by the primary coil to induce an electrical voltage in the secondary coil. By regulating the amount of current in the primary coil, an engineer can control the amount of induced voltage in the secondary coil, which can be used to control power in a device.The 2500R-74F is designed for very power limited applications, as it can only handle up to a maximum current of 1.2A. However, it is ideal for low power applications, such as headphone lines, as it can effectively filter out higher frequency currents while still allowing the desired frequencies through. Additionally, it can also be used in low-voltage regulated power supplies, where the voltage can be stepped down to multiple levels. Furthermore, the 2500R-74F is also commonly used in antenna drives, more specifically oscillator circuits, where it can be used to convert a single frequency source into a multi-frequency oscillation.The 2500R-74F is typically rated at a maximum voltage of 3.0V, however, it can be used in higher voltage applications as long as the current is limited. For applications over the 3.0V rating, the 2500R-74F must be connected in series with other inductors to divide the total voltage. Additionally, the 2500R-74F is designed to be used in low temperatures, as it can handle temperatures up to 70°C.In conclusion, the 2500R-74F Is a fixed inductor designed for very low-power applications, such as headphone lines, low-voltage regulated power supplies, and antenna drives. It utilizes the electromagnetic principles to convert an input current into an output voltage on its secondary coil. The 2500R-74F is typically rated up to a maximum voltage of 3.0V and can handle up to 1.2A of current. It is designed for low-temperature environments, and can also be used in higher voltage applications by connecting multiple inductors in series.
