Fixed Inductors

Inductors are electrical components that store energy in the form of magnetic fields. The CR75-180KC is a type of fixed inductor, meaning it has a fixed amount of stored electrical charge. The CR75-180KC is a popular choice among designers due to its large range of operating currents and voltage ratings.

The CR75-180KC application field includes various industrial sectors, including power systems, alternative energy, and telecom. It is commonly used to store energy when used in circuits, such as switching circuits or circuits with limited voltage sources. It can also be used to filter out radio frequency interference in audio systems, as well as for transient suppression in some industrial applications.

The working principle behind the CR75-180KC fixed inductor is based on Faraday’s Law of Induction. This law states that a changing magnetic field will induce an electric current in a nearby conducting loop. The magnetic field is created by an electric current passing through a loop of wire, which is wrapped around a magnetic material (called a core). When such an electric current changes, the magnetic field will likewise change, inducing a voltage into the loop of wire, which is then stored as energy in the form of the inductor’s magnetic field.

The CR75-180KC fixed inductor consists of a cylindrical iron core covered by two coils of wire, known as the primary and secondary windings. The primary winding carries the input current, and the secondary winding is connected to the output. When current passes through the primary winding, a magnetic field is created, which induces a voltage in the secondary winding. The amount of induced voltage is proportional to the rate of change of the primary current, as per Faraday’s Law.

The magnetic field generated by the CR75-180KC fixed inductor can also be used to reduce AC ripple voltage in power supplies. AC ripple is the periodic fluctuation of the DC voltage output by a power supply, and can cause significant noise and current flow disturbances within a circuit. The inductor reduces the ripple by storing energy during times of high voltage, then releasing it when the voltage drops below a certain level.

The CR75-180KC fixed inductor is a popular choice for a number of applications due to its high currents and voltage ratings. With proper design, the inductor can provide stable performance, even under high currents. Its wide range of operating currents and voltage ratings also makes it suitable for a wide range of industrial applications, from power systems to alternative energy and telecoms.
