Fixed inductors, also known as Choke coils, are passive electrical components made from conducting wire wrapped around a core material with a ferromagnetic and a high permeability. They are mainly used to limit current and store energy in applications like filters, oscillators, transformers, and radio frequency matching networks. The ELJ-NCR68JF is a high performance fixed inductor that is suitable for use in the various fields of radio and digital circuitries.

The ELJ-NCR68JF features a wide inductance range and is characterized by low resistance and high Q-value. It is also RoHS compliant and has a terminal pitch of 2.4mm. It has the dimension of 6.8mm x 5.6mm x 4.5mm and is produced with a special sintered ferrite core to minimize losses due to leakage flux. This ensures accurate operation in digital signal lines even at low frequencies.

The major application fields of ELJ-NCR68JF are power supply circuits, signal transmission lines, and measurement circuits. It is widely used in audio equipment, medical equipment, home appliances, automotive electronics, communication systems, and instrumentation systems. As for its working principle, the ELJ-NCR68JF fixed inductor works on the concept of magnetic reluctance. Its design makes use of magnetic lines of force which are established within each layer, and these lines of force cause the core to become magnetically saturated. The flux generated by the internal electrical coils is proportional to the current. This flux creates a magnetic field which opposes the applied field and as the core becomes more and more magnetically saturated, the flux density reduces. This reduces the negative backlash in the coil so that the current flow is restricted and this will enable the current to be more stable.

Overall, the ELJ-NCR68JF is an ideal choice for applications requiring a high level of performance such as signal processing, signal transmission, radio frequency circuits and power supplies. Its low resistance, high Q-value, and RoHS compliance make it a reliable and durable option for use in a variety of applications. Additionally, the sintered ferrite core enables the device to absorb leakage flux for consistent current operation, even at low frequencies.
