Fixed inductors, sometimes referred to as chokes, are passive components used in electronic circuits. Fixed inductors are usually composed of a coil of insulated copper wire, and have a variety of uses depending on the application. In this article, we will discuss the NLV25T-010J-EFD and its use in the electronics industry, as well as the working principle behind fixed inductors.

The NLV25T-010J-EFD is a through-hole fixed inductor from Panasonic that is designed for high stability, low noise, and high efficiency. It has an inductance of 10 μH, and a resistance of 10.2 mΩ. The component has a maximum operating temperature of 125°C, and a maximum voltage rating of 50 Vdc. The component is available in a package size of 22 mm × 6.5 mm.

The NLV25T-010J-EFD is typically used in power management, motor drive, and automotive applications. In power management, it can be used as a space saving solution for DC-DC converters, as well as a low noise filtering solution for power supplies. In motor drive applications, it can be used to reduce power losses and improve efficiency. In automotive applications, it can be used as a noise and voltage spike suppressor, as well as an EMI filter.

In order to understand how fixed inductors work, we need to understand the principles of electromagnetic induction. The concept of electromagnetic induction can be traced back to the earliest experiments in electricity by Michael Faraday, who discovered that a time-varying magnetic field could induce a current in a conductor. This phenomenon, known as Faraday’s Law, states that a change in the magnetic flux through a given area will induce an electromotive force, or EMF. In addition, Faraday’s Law states that the magnitude of the induced EMF is proportional to the rate of change of the magnetic flux.

In a fixed inductor, the coil of wire acts as a core upon which a magnetic field is generated. When a current passes through the coil of wire, the changing magnetic flux induces a voltage across the coil. This voltage opposes the applied voltage, thus limiting the flow of current in the circuit. The amount of opposition to the applied voltage is determined by the inductance of the inductor – the larger the inductance, the greater the opposition.

This concept of induced voltage can be used to filter out high frequency noise and voltage spikes from a circuit. By connecting an inductor in series with a circuit, the changing magnetic flux will induce a voltage in the inductor that will oppose any externally-induced voltage. This allows the inductor to act as a low-pass filter, suppressing frequencies above its cutoff frequency. The NLV25T-010J-EFD can be used in this manner, offering good noise and EMI suppression for power management, motor drive, and automotive applications.

In summary, the NLV25T-010J-EFD is a fixed inductor from Panasonic designed for high stability, efficiency, and low noise. It is suitable for power management, motor drive, and automotive applications, and can be used as a space saving DC-DC converter solution, a low noise filtering solution, and a noise and voltage spike suppressor. The working principle of fixed inductors is based on Faraday’s Law of electromagnetic induction, whereby a change in the magnetic flux through a given area will induce an EMF. This induced voltage opposes the applied voltage, thus limiting the flow of current in the circuit.
