Fixed Inductors

Fixed inductors are electronic components that store energy in electric fields. These components consist of a magnetic core wound with one or more insulated wires. The electric charge stored in the field is transferred to electric current flowing through the inductor when a voltage is applied across it. This makes them useful in various kinds of electronic circuits and applications.

CDC4D20NP-472KC Application Field and Working Principle

The CDC4D20NP-472KC is a fixed inductor designed specifically for high-frequency operation. It is capable of storing electrical energy at frequencies from up to 500 MHz with an inductance of 4.72 mH. It is suitable for use in high-power applications such as telecommunications, radar and aviation, as well as industrial electronics.The core of the fixed inductor consists of an iron or ferrite material with wire wound around it. A varying electric current is generated when an alternating voltage is applied to the inductor. This current generates an electric field in the core, which stores the energy. As the voltage returns to its original value, the energy is released back into the circuit.The design of the CDC4D20NP-472KC has been optimized for reliability and efficiency. It has a wide temperature range and can operate from -25oC to + 125oC. The winding is insulated to prevent damage caused by short-circuiting, and the overall construction of the component is robust.The key factor for determining the quality of the fixed inductor is the number of turns per coil winding. This affects the performance of the inductor in terms of its resistance and inductance. The CDC4D20NP-472KC has five turns per winding for a total of 10 windings, resulting in a high-frequency response.The other factor in determining the performance of the fixed inductor is its self-resonating frequency. The CDC4D20NP-472KC has an SRF of 900 MHz, which ensures that it can handle high-frequency signals without distortion.Finally, the CDC4D20NP-472KC fixed inductor also has an internal discharge function. This feature allows the energy stored in the electric field to be released quickly, preventing overvoltage damage to the component.The CDC4D20NP-472KC is a versatile component with numerous applications. It can be used in noise filter circuits and for signal conditioning. It can also be used in power supply circuits, switching power supplies, radio and TV equipment, cellular base stations, and various other types of communications equipment.Overall, the CDC4D20NP-472KC fixed inductor is an excellent choice for use in high-frequency applications. It has a wide range of features that make it suitable for a variety of applications. The combination of a high-frequency SRF, multiple windings, and an internal discharge function makes it a reliable and efficient component.
