Fixed Inductors: CIH05Q18NJNC application field and working principle

Fixed inductors, or coil inductors, are electromagnets formed around a specific number of turns of insulated wire. They are often used in electronic circuits to store energy, to filter signals, and to provide electrical isolation. The CIH05Q18NJNC fixed inductor is a miniature, high-performance, high reliability device used in a variety of applications such as DC/DC converters, flyback transformers, buck and boost converters and other switching power supplies. In this article, we will discuss the CIH05Q18NJNC application field and how it works.The CIH05Q18NJNC is a low-profile, SMD chip inductor with a high self-resonance frequency and good Noise Immunity. It has low DCR, high SRF, and excellent current-handling capability, making it suitable for a wide range of applications. It also features RoHS compliance and Halogen-free construction, making it environment friendly.The CIH05Q18NJNC is used in DC/DC converters, flyback transformers, buck and boost converters and other switching power supplies, and in radio frequency and microwave circuits, among other applications. It is designed for high voltage and high current operation and can handle up to 10A currents and up to 100V DC.The CIH05Q18NJNC works by storing electrical energy in its magnetic core in the form of a magnetic field, like all inductors do. It has two terminals, the inductor and capacitor, connected in series. When an electrical current passes through the inductor, a magnetic field is created and stored in the core of the inductor. This stored energy is then released when the current changes, converting the magnetic field back into electrical current.The CIH05Q18NJNC helps to improve system power efficiency and reduce noise by providing input power for DC/DC converters, flyback transformers, buck and boost converters and other switching power supplies. The inductor helps to reduce high-frequency noise and ringing, which improves system performance and enhances user experience.The CIH05Q18NJNC is also used in RF and Microwave circuits. As the frequency increases, the capacitance in a circuit decreases and the inductance increases. The inductance of the CIH05Q18NJNC helps to maintain high-frequency signal integrity and control the phase shifts. This makes it ideal for RF switch circuitry and antenna design.In summary, the CIH05Q18NJNC is a high-performance, high reliability device used in a variety of applications. It is designed for high voltage and high current operation and is suitable for DC/DC converters, flyback transformers, buck and boost converters and other switching power supplies, and radio frequency and microwave circuits. The CIH05Q18NJNC works by storing energy in its magnetic core in the form of a magnetic field and releasing it when the current changes. This helps to improve system power efficiency and reduce high-frequency noise and ringing.
