Fixed inductors play an important role in the design of modern electronics. These inductors are used to store energy and control currents in circuits. The CDRH4D18NP-560NC is one of the most widely used fixed inductors for power supply applications and general-purpose circuit design. In this article, we will explore the application field and working principle of the CDRH4D18NP-560NC.

Application Field of CDRH4D18NP-560NC

The CDRH4D18NP-560NC is a popular high-performance, low-cost fixed inductor with an inductance of 4.7μH. It is designed for use in power supply circuits and can handle up to 2.5 A current. It has an operating temperature range of –40°C to +105°C and a maximum temperature rise of 85°C. It is designed to meet the requirements of a wide range of electronic applications, including DC-to-DC power converters, mobile phones, laptop power supplies, and consumer electronics.

In addition, this fixed inductor is ideal for power supply circuits that require high power density and fast transient response. The low-resistance design allows for low input-to-output impedance and high-speed full and partial wave rectification.

Working Principle of CDRH4D18NP-560NC

The CDRH4D18NP-560NC is a type of fixed inductor that utilizes a polarized core and an electromagnetic field within its winding. This field helps the inductor store energy and control the flow of currents in a circuit.

The inductor works by using the Faraday’s law of induction to generate an induced electromagnetic field. The current through the inductor is proportional to the magnitude of the applied voltage and the time rate of change of the flux. This induced field opposes the change in the current, which in turn reduces the rate of change of the flux. This process is known as “self-inductance”, and it is what allows the inductor to store energy. The more current that passes through the inductor, the greater the induced field and the more energy that is stored.

When the power to the inductor is switched off, the stored energy is released back into the circuit. This phenomenon is known as “reverse-induction” and is due to Lenz’s law. The current that is released creates a voltage drop across the inductor, which can be used to power a load. The amount of energy that is stored in the inductor depends on the amount of current that is being applied. The greater the current, the more energy is stored.

The CDRH4D18NP-560NC is a great choice for power supply designs that require fast response times and high power density. It can handle up to 2.5 A current and has an operating temperature range of –40°C to +105°C. It is suitable for DC-to-DC power converters, mobile phones, laptop power supplies, and consumer electronic devices.
