Fixed InductorsFixed inductors are electronic components that store energy in the form of a magnetic field when electric current flows through them. They are generally used in electronic circuits to act as filters, configurable signal paths, and frequency control components. The RCH664NP-7R2M is a fixed inductor that has a wide range of applications and utilizes several methods of operation. ApplicationsThe RCH664NP-7R2M fixed inductor is primarily used in power supplies, DC-DC converters, among others, and provide excellent features in terms of power handling, inductance, and operating temperature range. Its wide operating temperature range of -40°C to 150°C (-40°F to 302°F) makes it suitable for a variety of industrial, automotive, and military applications.The RCH664NP-7R2M fixed inductor can be used to reduce power supply noise, suppress high-frequency electrical noise, and cushion sudden voltage changes. It also helps to ensure longer life and lower power consumption in power supplies. The product is RoHS compliant and delivers low voltage ripples, which makes it perfect for cost-sensitive applications. Working PrincipleThe RCH664NP-7R2M fixed inductor operates on Faraday\'s Law of Induction. This law states that a voltage is induced in a conductor when the conductor moves through a magnetic field. When an electric current passes through the coil, a magnetic field is created, and this magnetic field induces a voltage in the coil. The magnitude of voltage depends upon the rate of change of the magnetic field, which in turn is determined by the rate of change of the current passing through the coil.The product also utilizes mutual induction, which occurs when two winding’s magnetic fields interact, resulting in a transfer of magnetic flux. When a current flows through one winding, the magnetic field generated induces an electromotive force in the other winding and can also induce a current in the winding. This alternating current opposes the current in the first winding, resulting in a reduction of the current. The application of series and parallel inductors helps to even further increase and improve the overall efficiency of the device. When inductors are connected in series, the resultant inductance is increased while the current is decreased. On the other hand, when inductors are connected in parallel, the resultant inductance is decreased while the current is increased. ConclusionThe RCH664NP-7R2M fixed inductor is a versatile product with a range of applications and operating principles. It provides excellent features in terms of power handling, inductance, and operating temperature range. It is also RoHS compliant and delivers low voltage ripples, ideal for cost-sensitive applications. The product utilizes Faraday’s Law of Induction and mutual induction, as well as series and parallel inductors, to ensure greater efficiency and performance.
