Fixed Inductors

Inductors, or coils, are two-terminal passive electronic components that store energy in a magnetic field when electric current passes through them. Inductors are a key component in many electrical circuits and are used to provide inductive reactance and electromagnetic shielding. In particular, fixed inductors are components whose inductance is exactly known and holds a fixed value. The 4922-391J is one example of a fixed inductor widely used in modern electronic devices. This article will discuss the application field and working principle of the 4922-391J.The 4922-391J is a general-purpose inductor used in LCD television sets and computer monitors. It is designed to provide high-speed performance and excellent thermal stability. The excellent thermal stability and low-loss characteristics make it ideal for use in power electronics applications. Furthermore, the 4922-391J has a high self-resonance frequency and a flat inductance vs. frequency response, which make it suitable for digital switching application.The 4922-391J is a Class 2 miniature SMD inductor and has a one-piece construction. It is constructed with a ferrite core and two windings of coated copper wire. The core and windings provide excellent shielding and high level of inductance. The rated inductance is 100nH and tolerance ± 5%. The 4922-391J has a permeability rating of 7500 and a rated current of 1.2A. It has a total size of 10.4mm x 8.95mm making it suitable for placement on compact motherboards.The working principle behind the 4922-391J is based on Faraday\'s Law of Induction, which states that changing magnetic flux through a circuit induces an electromotive force (EMF) in that circuit. This EMF is proportional to the rate of change of flux, as well as the circuit\'s inductance. The inductance of a circuit is determined by the total number of turns in the coil, the diameter of the coil, and the material of the core. When AC current passes through the 4922-391J, it builds and collapses a magnetic field. The collapsing field then induces a voltage opposite in phase to the supply voltage. This opposing voltage reduces the supply voltage, and the reduction in voltage is equal to the amount of inductance. This inductance allows the 4922-391J to act as an energy-storing device and helps regulate the current in a circuit, making it suitable for power consolidation tasks.In conclusion, the 4922-391J is a popular fixed inductor used for power electronic applications. Its high self-resonance frequency, low-loss characteristics, and excellent thermal stabilization make it particularly suitable for LCD television sets and computer monitors. It works on the principle of Faraday\'s Law of induction, where the EMF is proportional to the rate of change of flux, as well as the coils inductance.
