PM125S-470M

Fixed inductors are a type of passive electromagnetic component that store energy in an electromagnetic field. They consist of a coil of insulated wire surrounded by a core of ferromagnetic material and, when placed in an alternating current circuit, they store electrical energy as a magnetic field. In this article, we will discuss the application field and working principle of the PM125S-470M fixed inductor, a type of Coilcraft component.

The PM125S-470M fixed inductor is designed for use in several applications, including, but not limited to, buck and boost converters, forward converter circuits, and adaptive gain control circuitry. Additionally, due to its low profile, it can be used in a wide range of compact applications, such as mobile phones or computers.

The fixed inductor has an inductance of 470 μH and a current rating of 115 mA. It is rated to operate at frequencies from 0.1 MHz to 1.2 MHz and temperatures from –40°C to 105°C. Its saturation current is 1.2 A and its self-resonant frequency is 7.2 MHz. Moreover, the PM125S-470M has a unique feature – its shield can be connected directly to ground, providing a low-cost alternative to mounting the shield externally.

The PM125S-470M fixed inductor works by generating a magnetic field when a current passes through its coils. This magnetic field then stores the incoming energy and dissipates it into the surrounding environment. As the frequency of the input current increases, the size of the surrounding magnetic field increases as well. This increase in field size helps to reduce the effect of electromagnetic interference.

The size of the PM125S-470M\'s magnetic field is determined by the size of its core, the number of turns in its coil, and the rate at which energy is dissipated. The inductance of the fixed inductor is also affected by the permeability of the core material as well as the distance between the core and the shield. Additionally, the inductor\'s performance can be optimized by changing the orientation of its components and adjusting the size of the core and the number of turns in the coil.

In conclusion, the PM125S-470M fixed inductor is a versatile component that can be used in a wide range of applications, from buck and boost converters to adaptive gain control circuitry. Its low profile and extensive range of features make it a suitable component for a variety of circuit designs. Additionally, its unique shield feature allows it to be used in low-cost applications, such as mobile phones or computers.
