Fixed inductors, also known as chokes, are electrical components that are primarily intended to introduce inductance into a circuit. Inductors are often used in power supplies, filters, and audio circuits. The IFCB0402ER8N2S is an example of a fixed inductor, and its application field and working principle are discussed in detail below.

Application Field of IFCB0402ER8N2S

IFCB0402ER8N2S is a small, surface-mounted fixed inductor designed for high volume and cost-sensitive consumer electronics applications. It is commonly used in DC-DC converters, cell phones, media players, and other consumer electronics. The inductor is suitable for both automated assembly and manual soldering, and is compliant with both commercial and safety standards.

The IFCB0402ER8N2S is capable of providing a steady inductance of 0.9nH over a wide range of temperatures (-55°C to +125°C). It has a saturation magnetic field of 1.0mT (10mT max), and a DC resistance of 0.025ohm. It is a ferrite core device, with a 3-layer bobbin construction and a molded resin body. It has a fairly low core loss (less than 10% at 0.5MHz) and is stable under high temperatures.

In addition to its application in consumer electronics, the IFCB0402ER8N2S can also be used in other applications such as automotive and lighting systems. It is especially suitable for use in DC/DC converters, filters, and antenna circuits.

Working Principle of IFCB0402ER8N2S

The IFCB0402ER8N2S works on the principle of electromagnetic induction. This principle states that when a conductor such as a coil is exposed to a changing magnetic field, it induces current in the coil. The current in the coil then creates a magnetic field of its own, that opposes the change in the original magnetic field.

This phenomenon is usually represented by Ampere’s Law, and can be explained as follows: When a conductor moves through a magnetic field, it creates a voltage in the conductor. This voltage then results in a current flow through the conductor. If the magnetic field around the conductor changes, then the voltage in the conductor will also change. This results in an induced current flow in the conductor. The strength of the induced current will depend on the strength of the changing magnetic field and the size of the conductor.

In an IFCB0402ER8N2S inductor, the changing magnetic field is provided by a coil of insulated copper wire wound around a ferrite core. The core serves to increase the magnetic field in the inductor, and the size of the conductor (the wire) determines the strength of the induced current. When high frequencies are applied to the inductor, the core causes the current to increase more quickly, thus providing the inductor with its inductance value.

In summary, the IFCB0402ER8N2S is a type of fixed inductor. It is suitable for use in high-volume and cost-sensitive consumer electronics applications, including DC/DC converters, filters, and antenna circuits. It works on the principle of electromagnetic induction, and has a wide operating temperature range (-55°C to +125°C). It has a saturation magnetic field of 1.0mT (10mT max), and a low DC resistance of 0.025ohm. It has a fairly low core loss (less than 10% at 0.5MHz), and is stable under high temperatures.
