IntroductionFixed inductors are electrical components that are designed to offer electromagnetic coupling between two or more circuits, including power converters, amplifiers, DC-DC converters, and other devices that require inductance. The 4922R-51J is a type of fixed inductor designed to provide a high-quality, stable inductive load in a wide range of applications.Mechanical CharacteristicsThe 4922R-51J is designed to provide high-frequency performance with low-loss performance due to its tight construction design. This device is constructed with two opposite flat magnetic plates that are held together with a copper strap and connected to a small electric terminal. To reduce leakage and harmonic content, a thin film coating is applied to the surface of the inductor. The 4922R-51J features high-quality termination and easy mounting with a strong, mechanically robust package.Electrical CharacteristicsThe 4922R-51J has an inductance of 4.9uH, a maximum operating frequency of 150MHz, a maximum DC current of 1.2A, and a maximum DC resistance of 85mΩ. This inductor is rated to withstand a voltage of 20V, an intermittent DC offset of 0.5V, and an operating temperature range of -40 to +105°C. The device supports a frequency range of 10kHz to 150MHz, and is designed to provide high-efficiency performance.Application FieldThe 4922R-51J is a high-performance, fixed inductor designed for a wide range of applications in consumer electronics, automotive electronics, telecommunications, and power converters. The inductor is suitable for use in power supplies, power converters, power amplifiers, voltage regulators, and motor control applications. It can be used in DC-DC converters, DC-AC converters, switched-mode power supplies, and other high-frequency electronic circuits.Working Principle The working principle of the 4922R-51J is based on the principle of electromagnetic induction. The inductor stores energy by intercepting a changing magnetic flux. The 4922R-51J uses a metal core surrounded by a conductive coil. When an alternating current passes through the coil, a changing magnetic field is created. This changing magnetic field is intercepted by the metallic core, thus storing energy in the form of magnetic flux. When the current ceases, the stored energy is released as an alternating current.
