Fixed Inductors

Fixed inductors are electronic components that are designed to store energy in the form of an electromagnetic field. They are used in a variety of applications, ranging from analog circuit design to digital board-level interfacing. One of the most common types of fixed inductors is the RCH855NP-222K type, which is commonly used for switched-mode power supplies (SMPS).The RCH855NP-222K fixed inductor is a 0.8Ω, 5.5A rated component, with a nominal inductance of 22μH. It is rated for an operating temperature of up to 105°C, and a maximum temperature of 125°C. It is typically constructed from a ferrite core material, with copper wire windings. The ferrite core is extremely efficient at storing energy, which makes this type of fixed inductor particularly suitable for applications such as SMPS.The primary advantage of the RCH855NP-222K fixed inductor is its low resistance. By using a ferrite core, the inductor has an extremely low DC resistance, reducing the losses associated with current passing through it. The copper wire windings also help to reduce these losses, as they minimise the amount of resistance in the current path. This means that the inductor can handle more current without becoming overly hot, which is beneficial in many applications.The RCH855NP-222K fixed inductor is commonly used in applications such as flyback converters, buck-boost converters, and forward converters. It is also used in power filters, including primary and secondary stages. In all of these applications, the low DC resistance of the inductor is critical, as it helps to minimise losses, and allows the component to provide more current to the circuit.The RCH855NP-222K fixed inductor also has excellent high-frequency performance, which makes it an ideal choice for applications where the inductor must operate at frequencies above 100kHz. This is due to its low core losses, which allow the inductor to maintain stable performance even at high frequencies.Overall, the RCH855NP-222K fixed inductor is an excellent choice for use in many applications. Its low DC resistance, high-frequency performance, and excellent energy storage capabilities make it an ideal solution for a variety of applications, including SMPS, flyback converters, and power filters.
