Fixed inductors are electrical components that are used to provide an inductance to a circuit. They are commonly used in power supplies, audio amplifiers, and various other electronic components. The ELJ-NA4R7JF is a fixed inductor that can be used in a variety of applications.

The ELJ-NA4R7JF is a small, dual-coil inductor that can provide a wide range of inductance values. The dual coils allow the user to vary the inductance by adjusting the number of turns of each coil. Also, the inductor has a built-in thermistor that can be used to monitor the temperature of the coils.

The ELJ-NA4R7JF can be used in power supplies, voltage regulators, audio amplifiers, and other circuits that require inductive filtering or noise suppression. It is also suitable for RF and EMI applications. The thermistor allows for temperature monitoring and can help to prevent overloads and circuit failures.

The working principle of the ELJ-NA4R7JF inductor is based on the principles of inductance. Inductance is a property of a circuit whereby a current passing through it results in a magnetic field being created around it. This magnetic field will induce a voltage in another portion of the circuit in proportion to the amount of current that passes through it.

The magnetic field that is created by the ELJ-NA4R7JF is proportional to the number of turns in each of its two coils. When the inductor is connected to a power source, a current will pass through it and create a magnetic field. This magnetic field will induce a voltage in the other connected portion of the circuit. This induced voltage will be proportional to the amount of current that passes through the inductor.

The ELJ-NA4R7JF inductor can also act as an electrical noise filter. It is used to suppress high-frequency electrical noise, such as that created by digital circuitry. This is achieved by connecting the inductor in series with components that are susceptible to noise and providing a low-impedance path for the noise. This prevents the noise from reaching other components in the circuit, thereby protecting them from damage.

In short, the ELJ-NA4R7JF is a fixed inductor that can be used in a variety of applications. It provides an adjustable inductance and can also be used as an electrical noise filter. The thermistor allows for temperature monitoring and helps to prevent overloads and circuit failures. The working principle of the inductor is based on inductance and results in an induced voltage that is proportional to the amount of current that passes through it.
