Fixed inductors are widely used in many electronic products because of their advantages in applications such as power supplies, filtering, timing, and tuning. ELJ-FC101KF is a fixed inductor designed by Panasonic, and it is suitable for general purpose applications. This paper discusses the application field and working principle of the ELJ-FC101KF fixed inductor.

The ELJ-FC101KF fixed inductor has a 6.0 mm width, 10.9 mm length, and a height of 1.85 mm, making it suitable for space-saving applications. It is made of ferrite, which has good heat dissipation and the characteristics are stable over a wide temperature range for increased reliability. Additionally, the maximum rated current of the inductor is 2.79 Amps, and the inductance range of the inductor is 0.45 – 47 µH.

One of the main applications of the ELJ-FC101KF fixed inductor is in power supplies. A power supply is an electronic device that takes input voltage from a source such as a household outlet and gives a desired output voltage as per the requirement. The ELJ-FC101KF inductor can be used in a switch mode power supply (SMPS) as it supplies constant current, making it suitable for low-noise operation. Additionally, it is also used in DC-DC converters, which is another type of SMPS used for the conversion of DC from one voltage level to another.

Apart from power supplies, the ELJ-FC101KF fixed inductor is also used for signal filtering and provides better frequency-domain performance than traditional capacitors. In addition, it is used for timing and tuning applications where its high inductance value is beneficial. For example, it is used in crystal oscillator circuits, which generate a fixed frequency which is used for precise timekeeping.

The working principle of the ELJ-FC101KF fixed inductor is based on Faraday’s law of induction. Faraday’s law states that when a magnetic field is applied to a conductor, it induces a voltage across the conductor. By winding a conductor into a coil, a stronger magnetic field can be generated, thus enhancing the induced voltage. The ELJ-FC101KF inductor consists of many coils wound together, which generate a magnetic field when a current flows through them. This magnetic field, in turn, creates a voltage across the windings that opposes the current, thus creating a resistive effect and allowing the inductor to store energy.

To summarize, the ELJ-FC101KF fixed inductor is widely used in power supplies, signal filtering, timing, and tuning applications. This fixed inductor is highly reliable and has a wide temperature range, making it suitable for many types of applications. Additionally, it works on the principle of Faraday’s law of induction, where the inductor stores energy and creates a resistive effect when a current flows through it.
