Fixed inductors are electrical components ideal for electrical applications that require a range of inductance values, such as a motor, an amplifier, or a switch. They are especially useful for filtering out AC noise. The two main types of fixed inductors are air-cored and ferrite-cored. The 8230-78 is a type of ferrite-cored fixed inductor, and its application and working principle are discussed in this article.

Structure of the 8230-78

The 8230-78 is a ferrite-cored inductor with a hollow winding form inside which is filled with an epoxy resin. The coil is made of high quality polyurethane copper wire. The coil is then encapsulated with epoxy resin. The exterior of the inductor is usually made of ABS or nylon material, and is sealed with waterproof tape.

Application

The 8230-78 is mostly used in the filters, DC-to-DC converters, and power supplies of computers, home appliances, and automobiles. It is especially useful in filtering electromagnetism interference, power conditioning, switching mode power supplies, electronic ballast for lighting, and the like.

Working Principle

The working principle of a fixed inductor can be understood by starting with the concept of Faraday’s law of induction. This states that a voltage is induced into a coil when the number of turns of wire in the coil are altered by a magnetic field. When the number of turns in a coil increases or decreases, it creates a back-EMF or a back voltage in the coil, resulting in an inductance. So when the current in the coil is increased, the magnetic field increases, inducing the voltage and increasing the inductance. Similarly, when the current is decreased, the voltage and inductance are also decreased.

In the case of the 8230-78, the inductor consists of a coil winding and a ferrite core. The coil is made of high-quality copper wire, and the core is made of a ferrite material, which is a type of magnetically soft material. The ferrite core intensifies the magnetic field created by the coil winding, thus increasing the inductance. The inductance can then be adjusted by manipulating the current or changing the number of turns in the coil.

Benefits of 8230-78

The 8230-78 offers several advantages for various applications. First, it has a high precision inductance, which is important for filtering out AC noise. It also has a low DC resistance, reducing heat and overall losses. The small size and low weight are another benefit, as it can be easily installed. Finally, it is highly reliable, and is designed to have a long life and be resistant to vibration and shock.

Conclusion

The 8230-78 is a type of ferrite-cored fixed inductor, which is used in many electrical applications. Its structure consists of a hollow winding form filled with epoxy encapsulated in ABS or nylon material. It works by inducing a voltage into a coil when a the number of turns of wire in the coil are altered by a magnetic field. The 8230-78 offers several advantages for applications such as filtering out AC noise, reducing losses, and being small and lightweight, as well as being highly reliable.
