Fixed Inductors
Fixed inductors are electronic components used for tasks such as filtering, blocking, current limiting, and impedance matching. They are widely used in telecommunications networks, power grids, sound systems, and computers. The 2890R-38K is a type of fixed inductor and is particularly suitable for telecommunications networks, where it is used to provide inductive filtering.The 2890R-38K is an axial-type fixed inductor made from ferrite cores with an inductance value range of 0.9µH to 10µH. Its cut-out on the outside of the case is approximately 5.08mm in diameter, and its pins are 1.02mm in diameter. As a result, it is ideal for high-density circuit designs in telecommunication and portable electronic equipment. It is also equipped with an enlarged slot to minimize noise when soldering.The 2890R-38K is especially useful in LD networks in telecommunication networks. LD networks, or inductive-divide networks, convert higher-frequency signals to lower frequencies. This is because inductors can block higher-frequency signals due to their high reactance. The 2890R-38K can block the unwanted high-frequency signals while also enabling easy soldering and and a small form factor.The 2890R-38K has a wide range of applications in telecommunications. It is used for filtering, blocking, impedance matching, and current limitation in microwave antennas, base stations, and earth receiving equipment. The LD network is a must for any LD circuit that requires a low operating frequency. It can also be used for power supply filtering, as the inductance value of the fixed inductor caps the current and, as a result, prevents interference from entering the power supply.The working principle of the 2890R-38K is based on Faraday\'s Law of Induction, which states that a voltage is induced by a changing magnetic field. When an alternating current passes through an inductor, it creates a magnetic field, which in turn induces a voltage in the inductor. This voltage is then transformed into an output signal, either by means of a diode or a transistor. By controlling the frequency and amplitude of the current, the 2890R-38K can be used to filter, block, or convert signals.The 2890R-38K is a versatile and reliable fixed inductor suitable for use in all kinds of telecommunications networks. Its small size and easy soldering process make it ideal for high-density circuit designs, while its inductance value range make it ideal for LD networks. Its working principle is based on Faraday\'s Law of Induction, and its application field is wide, ranging from power supply filtering to signal conversion.The specific data is subject to PDF, and the above content is for reference
