Fixed InductorsIntroductionFixed inductors, also called chokes, are electronic components used to induce high impedance at input and output stages of amplifiers and prevent unwanted frequency interference. Typically, these fixed inductors have two main parts, an inductor core and an air gap. The core is the material that stores the inductance while the air gap blocks the rate of current flow.1008R-391J application field and working principle The 1008R-391J fixed inductors are made from ferrite materials. These materials have the characteristics of high electrical resistance and low hysteresis loss, making them ideal for applications where high impedance is required. The product is an RFID reader antenna and works by adding inductance to the broadcast signal, thus decreasing the amount of noise and interference it produces.The 1008R-391J fixed inductor is also useful for providing energy storage in alternating current (AC) applications. In these systems, the inductor core stores and then releases energy rapidly, allowing for smoother, more efficient current flow in the device or circuit. It also helps to reduce power losses as it has a low resistance at lower frequencies.The 1008R-391J is a great choice for high impedance applications. It also works for computer memory back-up and storage. It is an effective way to reduce power losses due to voltage fluctuations and also helps to prevent short circuits.In addition, the inductor is also popular in wireless communication, including cellular phones, base stations, and radio networks. It helps to filter out unwanted signal noise and interference, allowing for better reception and improved communication. It also helps to reduce the total cost of ownership.ConclusionThe 1008R-391J fixed inductors are great for any application where high impedance is required as it has excellent impedance characteristics and can be used for energy storage. The product is also popular in wireless communication and storage systems as it helps to reduce power losses and improve reception. Overall, this product is a great choice for any high-impedance applications.
