Fixed inductors, also known as coils, chokes or reactors, are components that store energy in the form of a magnetic field. In applications that require high levels of power, like in AC motors, power supplies and controls, fixed inductors are the ideal choice. The ELJ-RF15NJF is a fixed inductor that is commonly used in a variety of applications.

The ELJ-RF15NJF is a shielded inductor with a tight tolerance of ±2%. It is constructed of an iron powder and is rated at 15uH with an inductance tolerance of 5%. The device is capable of handing up to 16A of current and has a saturation current of 11.4A. The inductor features an electrostatic shield to protect against signal interference, reducing EMI and RFI. The inductor\'s case is made of a flame-retardant material, making it very resistant to heat and is suitable for operation in an environment of up to 125°C.

The ELJ-RF15NJF is used in a variety of applications, such as automotive, computer, power supplies and controls. In automotive applications, the fixed inductor is used in airbag ECUs, air conditioning modules and intermittent control units. In computer applications, the inductor can be used in DC/DC converters, DC/AC inverters, monitors and power supplies. The device can also be found in power supplies and controls, for power factor correction (PFC), voltage ripple control, and noise reduction. Additionally, the inductor can be found in medical devices and LED lighting.

The ELJ-RF15NJF works by converting an alternating current (AC) into direct current (DC). It does this by utilizing a process called inductance, which is the property of a conductor whereby a changing current induces an electromotive force (EMF) in the conductor. The EMF creates a magnetic field around the conductor which is proportional to the current flowing through it. This induces a reverse EMF in the conductor, which opposes the original EMF, giving rise to a magnetic field known as inductance.

When a voltage is applied to the ELJ-RF15NJF, the magnetic field created produces a flux around the coil. This flux cuts across the turns of the coil, inducing a counter EMF within the coil. This EMF is proportional to the rate of change of the applied voltage. This induces a current flow in the coil that is in the opposite direction to the applied voltage. This current is known as the “back EMF” which reduces the in-phase current flow, resulting in the conversion of AC current to DC current.

The ELJ-RF15NJF is an ideal fixed inductor for applications that require high power. Its tight tolerance and electrostatic shield make it a reliable and durable device. The ELJ-RF15NJF can be found in a variety of applications, ranging from automotive to medical devices and LED lighting, due to its suitable for operation in an environment up to 125°C.
