Fixed inductors, also known as choke coils, are often used as passive electrical components in the power and signal circuits of many electronic devices. The ELJ-NK3N9ZF is one such fixed inductor made by Panasonic Industrial Devices Sales Co. Ltd. This article will explain the applications and working principle of the ELJ-NK3N9ZF.

The ELJ-NK3N9ZF is a slim, surface mounted inductor designed to be used as an electronic component in various circuit configurations. It has an inductance of 0.028µH and a rated current of 490mA. The ELJ-NK3N9ZF is constructed using a ferrite core and insulated copper wire, and its footprint is 5.0 x 2.6mm. The small size and low profile design of this inductor make it ideal for use in space-constrained devices such as mobile phones and digital cameras.

ELJ-NK3N9ZF fixed inductors have a wide range of applications. They are commonly used in power supplies and power supply filters for DC–DC converters and inverters, to reduce the levels of noise and interference generated by power fluctuations. They are also used in filter circuits to reduce the level of noise and high frequency signals generated by AT pick-up coils, and in audio circuits to reduce noise generated by loudspeaker coils. In radio frequency receiver circuits, the ELJ-NK3N9ZF can be used as a detector coil to detect signal strength.

The working principle of the ELJ-NK3N9ZF is based on Faraday\'s law of induction. When a current flows through the inductor, a magnetic field is created around the wire by the magnetic flux generated by the current. This magnetic flux interacts with the core material to produce an opposing electric field which acts to reduce the flow of current in the inductor. This opposition to the current is known as inductance. This inductance has the added benefit of reducing the level of interference and noise created by the current.

The ELJ-NK3N9ZF has been designed to be used as a reliable and efficient way to reduce the level of interference and noise caused by current fluctuation. Its small footprint and low profile design make it suitable for use in space-constrained electronic devices, such as mobile phones and digital cameras. Its inductance of 0.028µH and rated current of 490mA make it suitable for many different power and signal applications.
