Fixed Inductors: CDRH3D18NP-120NC Application Field and Working Principle

Fixed inductors are one of the most popular components used in electronics. A fixed inductor is an inductor that operates on stored electrical energy; it consists of two components, an inductor coil and the magnetic core.The CDRH3D18NP-120NC is one of the most commonly used fixed inductors. It has a high operating frequency, making it perfect for high-speed circuit design, and a low resistance, allowing it to draw relatively little current. It is also less susceptible to electrical interference, making it a great choice for noise-sensitive applications.The working principle of the CDRH3D18NP-120NC is quite simple. When electricity is passed through the inductor, the induced magnetic field produces a back electromotive force (emf) which opposes the flow of the electricity. This back Emf induces a current in the coil, which generates an opposing magnetic field which counteracts the original magnetic field and cancels out the back emf, thus forming a complete circuit. The result is that for the same input voltage, the inductor will act as if it has a constant voltage drop across it, hence the name fixed inductor.The CDRH3D18NP-120NC is primarily used in consumer electronics and automotive applications where a constant voltage drop is necessary. It is perfect for high-speed data transfer and digital communication circuits. It is also widely used in audio amplifiers, power supplies, electronic capacitors, and military and aerospace equipment due to its low resistance and high operating frequency.The CDRH3D18NP-120NC is also often used in inductor-capacitor (LC) tank circuits, where it is used to create a high-impedance environment that allows the capacitor to charge and discharge quickly. By doing this, it creates an oscillating circuit which is used to generate and filter signals.It is also used as part of voltage regulators, as it can act as a stabilizer and prevent fluctuations in the output voltage. In this case, the inductor is used to filter out the high frequency noise signals, thus ensuring that the regulator provides a steady output voltage.The CDRH3D18NP-120NC is ideal for a wide range of applications due to its high operating frequency, low resistance, and stable performance under varying conditions. Its small size and low weight make it an attractive choice for a wide range of applications, and its durability ensures that it will provide reliable performance for many years.
