Fixed inductors are components of basic electrical circuits. They store energy in the form of an electromechanical force, and can also be used to transfer energy to other components. The 4922-471J Series Inductors are an example of inductors used in a variety of applications. They are designed to provide high current capacity and stable performance over a wide operating range, and are suitable for use in high frequency, power line and communications applications.

The 4922-471J is a fixed inductor with a tolerance of ±1%. It has a high self-resonant frequency of 26.5MHz in a 1uH package, and can achieve up to 40A continuous current without saturation. The device features a low ESR, making it an ideal choice for powertrain applications, where low loss and temperature stability are important. Its high power handling capability makes it suitable for use in inverter and DC link applications, where converter efficiency can be improved by reducing power losses.

The winding construction of the 4922-471J is shielded in a plastic case for protection against electrical noise. The shield also helps reduce the effects of stray magnetic fields, which can cause performance degradation. Its high inductance with tight tolerance makes it ideal for use in circuit designs with tight voltage and current requirements.

The 4922-471J series operates over a wide temperature range of -55°C to +125°C. It is RoHS compliant, and has excellent Solderability. These features make them suitable for use in high-temperature, high-reliability applications, where variations in temperature do not pose a problem.

The working principle of the 4922-471J Series is based on Faraday’s Law of Induction. When a current is applied to a winding, a changing magnetic field is generated in the coil, which induce a voltage in the opposing winding. This voltage is inversely proportional to the rate of change of the magnetic field. The current is limited by the inductance of the coil, which is determined by the number of turns, the shape, and the material used. The inductance of the 4922-471J is relatively high for its physical size, making it suitable for use in high-current applications.

In summary, the 4922-471J series fixed inductors are highly efficient components suitable for a vast range of applications. From inverters, power supplies, servos, and other powertrain applications, to automotive, telecommunications, and aerospace, these inductors are designed to provide reliable performance in rugged applications. With an operating temperature range of -55°C to +125°C, high current capacity, low ESR, and excellent solderability, the 4922-471J is an ideal choice for use in high-temperature, high-reliability environments.
