4501R-112M

Fixed Inductors

A fixed inductor is an electrical component that consists essentially of an insulated coil of wire, with or without a ferromagnetic core. Its basic function is to store energy in form of a magnetic field when electric current flows through the coil. The field is proportional to the amount of current passing through the coil and its geometry. Fixed inductors are also known as inductors and chokes.The 4501R-112M is a fixed inductor from ATI Inductors/Coilcraft. It is a cylindrical drum-core inductor wrapped in air-core-held wire. This inductor has a one-piece construction, meaning that the core and coil are a single unit. It has an exceptionally high self-resonance frequency and a low DC resistance for higher current flow. The 4501R-112M is designed for use in switched-mode power supply (SMPS) applications, such as Notebook PCs and industrial-grade panel computers.

Application Field

The 4501R-112M is designed primarily for use in switching power supplies. It is suitable for use in a wide range of power supply designs, from personal electronics equipment to industrial grade computers. It is suitable for use in applications where a high self-resonance frequency and low DC resistance are needed for increased current flow.

Working Principle

The basic working principle of the 4501R-112M is the same as other inductors. When electric current flows through the inductor, a magnetic field is generated which stores energy. This stored energy can be used to smooth out fluctuations in the current flow, and to filter the waveforms. When the current flow is switched off, the stored magnetic field collapses and generates a voltage, which can be used as a source for the new current flow. This prevents the current from abruptly stopping, thus providing a smoother transition between on and off states. This helps prevent power surges, which can damage sensitive electronic components.

Conclusion

The 4501R-112M is a fixed inductor which is designed for use in switching power supplies. Its one-piece design allows for a higher self-resonance frequency and lower DC resistance, thus allowing for higher current flow. It can be used in a variety of applications, from personal electronic devices to industrial-grade computers. Its basic working principle is the same as other fixed inductors: it stores energy in form of a magnetic field and uses it to help smooth out current fluctuations.
