Fixed Inductors are core components of electrical and electronic equipment, circuits and systems. The LQW04AN16NJ00D is a fixed inductor designed to provide inrush current limit and voltage-attenuating functions, making it useful in a variety of applications. This article looks at the application field and working principle of the LQW04AN16NJ00D and how it fits into the fixed inductors category.

The LQW04AN16NJ00D is most commonly used for applications in power conditioning and power factor correction (PFC). Power factor correction is the process of using an inductor to reduce the amount of reactive power in a power system, ensuring a power factor of 1 or greater. The LQW04AN16NJ00D can provide superior inrush current limit and voltage attenuation in these applications, as it has an inductance value of 5.6µH and a temperature coefficient of impedance (TCR) of ±100ppm/°C, in addition to low-inductance winding with no audible noise.

Another application in which the LQW04AN16NJ00D is commonly used is switching-mode power supplies. Switching-mode power supplies (SMPS) contain an inductor which is used to store energy from an input current and then releases it to the load. The LQW04AN16NJ00D can be used in this application due to its low-resistance winding, minimizing voltage ripple and enabling reliable operation of the power supply.

The working principle of the LQW04AN16NJ00D is based on Faraday’s law of induction, which states that when a conductor (made up of one or more wires) carrying a current is placed in a fluctuating magnetic field, an induced electromotive force is created in the conductor. This induced electromotive force is proportional to the rate of change of the magnetic flux passing through it. This means that as the current in the conductor changes, the magnetic field surrounding it changes, inducing a voltage in the conductor.

The LQW04AN16NJ00D is specifically designed to take advantage of this principle. It has an inductance value of 5.6µH, meaning it can effectively store energy from an input current and then release it to the load. Furthermore, its low-inductance winding enables tight voltage regulation and a low-profile package for easy mounting. The LQW04AN16NJ00D is temperature resistant due to its TCR of ±100ppm/°C.

In conclusion, the LQW04AN16NJ00D is a fixed inductor and is designed for use in applications such as power conditioning and power factor correction, as well as switching-mode power supplies. It works based on Faraday’s law of induction, inducing a voltage in the conductor as the current in it changes. Its specific features, such as low-inductance winding with no audible noise, a low-profile package, low-resistance winding and temperature-resistant properties, make it suitable for these applications.
