Fixed inductors are essential components in many electronic circuits that provide strict control over current and energy flow. The ELJ-QF2N4DF fixed inductor is one particular type of inductor designed for specific applications. This inductor has many features which make it a valuable addition to any designer’s toolbox.

Application field of ELJ-QF2N4DF

The ELJ-QF2N4DF fixed inductor is mainly used for switching power supplies, inverters, LED lighting, electronic ballasts, motor drives, and relay drivers. It offers an excellent performance and superior resistance to temperature cycling. Additionally, it tolerates higher temperatures than other inductors and has a high ripple current capability. For switching applications where a fast response is needed, the ELJ-QF2N4DF works well as it has a low inductance, as well as a low magnetizing current.

Working principle of the ELJ-QF2N4DF

The ELJ-QF2N4DF fixed inductor uses a wire wound in a coil in order to produce an electrical field. The coil is made up of copper wire, which is used to create a magnetic field around the coil. When electricity passes through the coil, the magnetic field created by the copper wire causes a change in the electrical current, resulting in an increase or decrease in the current’s intensity. This effect is known as inductance when the flow of electricity is stopped, the magnetic field stored in the coil dissipates and returns to its original state.

The ELJ-QF2N4DF fixed inductor also has a high frequency response with a low resistance. This allows the inductor to be used in high-frequency applications, such as radio transmitters and data transmission systems, as well as in low-frequency applications, such as power supplies.

The ELJ-QF2N4DF is made with a shielded construction which helps to reduce interference from other nearby components. It is also designed with a shielded ferrite core which reduces power losses that occur when current flows through it. Additionally, it has a high immunity to electrical noise caused by other components, making it ideal for use in noise-sensitive applications such as audio equipment.

The ELJ-QF2N4DF fixed inductor is a reliable and versatile component which can be used in a wide variety of electronic circuits. Its many features make it a valuable addition to any design engineer’s toolbox. Its ability to resist temperature cycling, handle high ripple currents, and reduce interference from other components make it a viable choice for many different applications.
