Fixed inductors are electrical components, also known as coils, chokes, and reactors, that store energy in the form of a magnetic field. The CDR74NP-120NC is an example of a fixed inductor specifically designed for use in AC power line filtering. In this article, we will discuss the application field and working principle of the CDR74NP-120NC.

Application Field

The CDR74NP-120NC fixed inductor is designed to be used in AC power line filters. The device is especially suitable for applications such as power supplies, high power drives, motor control, and other high frequency AC circuits that demand low resistance or high-flux inductors. Additionally, the device features high-end performance for power line filters including low resistance, low-saturation, self-healing, and high-frequency filtering. Triple-insulated windings also ensure optimal safety and reliability while reducing electromagnetic interference.

Working Principle

The CDR74NP-120NC fixed inductor operates using the phenomenon of mutual induction. When an AC current is passed through a wire, in this case the triple-insulated windings, a magnetic field is created around the wire. This magnetic field induces a current in a closely wound loop of wire, producing a current in the opposite direction. This current creates a magnetic field in the opposite direction, producing an opposing force against the original current. The result is a transfer of electrical energy from the primary winding to the secondary winding and an increase in the magnitude of the current.

The CDR74NP-120NC is designed with special cores that reduce the power loss due to the magnetic hysteresis and eddy current losses in the windings. This ensures that the device is able to maintain stable current levels over a wide range of frequencies.

Conclusion

The CDR74NP-120NC fixed inductor is an example of a fixed inductor specifically designed for use in AC power line filtering. The device is ideal for applications such as power supplies, high power drives, motor control, and other high frequency AC circuits that require low resistance or high-flux inductors.
