Fixed Inductors—CD43NP-3R3MC Application Field and Working Principle

A fixed inductor is composed of three parts: core, coil, and cover; and consumes energy to produce a magnet field. They provide inductance in a circuit that helps to store energy and regulate the current flow. Without inductors, the circuits would be simpler and store less energy, limiting their capability and usefulness in certain applications. CD43NP-3R3MC fixed inductors are an excellent example of a high performance application and they have various uses.

What is CD43NP-3R3MC?

CD43NP-3R3MC is a fixed inductor that is wrapped with color-coded PPTC (positive temperature coefficient) Type-2 wire that helps to reduce the risk of short circuits. It is a three-core type, which means it has three separate coils that are randomly wound around a single core. This type of inductor is typically used in DC/DC converters, DC/AC inverters, switch-mode power supplies, audio equipment, and other power electronics applications. The CD43NP-3R3MC has a three ohm resistance with 3300 uH inductance and a maximum AC current rating of up to 4.7 Amps.

Application Field

CD43NP-3R3MC fixed inductors have several different applications. One of the most popular applications is its use in DC/DC converters to increase the output voltage and current. The inductors are designed in such a way that they create a counter-emf (electromotive force) which then compensates for the minor voltage fluctuations, thus providing a smooth output current. CD43NP-3R3MC also works well in DC/AC inverters. In DC/AC inverters, the inductors store energy and supply it when required, resulting in a more efficient system with less power loss. CD43NP-3R3MC can also be used in switch-mode power supplies, audio equipment, and other power electronics applications.

Working Principle

The working principle of CD43NP-3R3MC is based on Faraday’s law of induction. According to this law, when an electric current passes through a wire, it creates a magnetic field around the wire, and the magnitude of this magnetic field is proportional to the strength of the current passing through the wire. The magnetic field created by the current in CD43NP-3R3MC causes electrons to flow from one coil to the next. This process is called electromagnetism and it is what produces the counter-emf, or the voltage stabilization effect, in DC/DC converters and DC/AC inverters. As the current flows through the inductor, the electrons produce a magnetic field that varies inversely with the current, thus providing the necessary voltage regulation. When the current reverses direction, the magnetic field created by the electrons and the inductance also reverse, resulting in an increase in the current flow in the opposite direction. This is how the inductors store energy in power supplies and inverters—the higher the current, the more energy is stored.

Conclusion

CD43NP-3R3MC fixed inductors provide a high performance solution for DC/DC converters, DC/AC inverters, switch-mode power supplies, audio equipment, and other power electronics applications. They are designed with three cores that are randomly wound around a single core, and they feature color-coded PPTC (positive temperature coefficient) Type-2 wire that helps to reduce the risk of short circuits. The working principle is based on Faraday’s law of induction, which states that when an electric current passes through a wire, it creates a magnetic field around the wire. CD43NP-3R3MC fixed inductors have a three ohm resistance with 3300 uH inductance and a maximum AC current rating of up to 4.7 Amps.
