Fixed inductors are electromechanical components used for storing magnetic energy in electrical circuits. CD43NP-680KC is a type of fixed inductor made of iron-cored coils that often stands in a cylindrical form. It is generally used for power factor correction and voltage regulation applications in power supplies and UPS systems. It can also be used to increase the inductance of other inductors in a circuit.

CD43NP-680KC employs a ferrite core, and its overall dimensions are 8 x 50mm. It has an inductance of 680mH between 1kHz and 100kHz, with an Rdc of 28Ω +/-10%. Its minimum internal current of 86A gives it a saturation of 3.6A, and its rated current is 95A. It also features a self-heating of 1.7℃ per watt in 5% tolerance

Applications of CD43NP-680KC include power-factor devices, motor control, filters, voltage stabilizers, power conditioning, and other areas where inductance is used. It can also be used for protection against overbearing currents and short-circuits. The inductor helps to control the flow of the current in the circuits.

The working principle of CD43NP-680KC is based on the Faraday law of induction. This law states that when a current flows through a wire, it creates a magnetic field around the wire. The application of this law is that when the magnetism interacts with the turns of a fixed inductor, it produces an electromotive force in the wire, which has an opposing polarity. This creates an inductance to resist changes in electric current through the inductor.

The CD43NP-680KC has the ability to maintain the constant current for a long period of time, even in case of high-frequency pulses. This makes it an ideal choice for applications where long or slow-current flows are needed. It is also suitable for circuits where there is a great deal of current fluctuation or load reversal.

Moreover, the CD43NP-680KC has excellent thermal resistance, thanks to its flexible plastic wrapping, which allows the inductor to have a higher temperature resistance compared to standard components. This makes the device more durable and reliable, particularly in situations, such as surges and short circuits, where the power rating is over the limit.

Overall, the CD43NP-680KC is a robust and reliable fixed inductor with a large application field. Its Faraday-law-based inductance, high current rating, and excellent thermal resistance make it an excellent choice for a wide range of uses in the industrial world.
