Fixed inductors are passive electronic components consisting of a coil of insulated wire wound around a ferrite- or poweder-core. They differ from variable inductors in that the inductance of the coil does not change over time or with external effects. Fixed inductors are connected in various ways, depending on the application. Generally speaking, they are found in all types of electronic circuits, including amplifiers, radio transmitters and receivers. PM74SH-120M-RC is an example of a fixed inductor.

The PM74SH-120M-RC fixed inductor is a compact, surface mounted component with an inductance of 120 µH and a rated current of 1.0A. It features an epoxy coating for added protection from dust, oil, and other contaminants. The component works by allowing electrical current to flow through the winding, creating a magnetic field which then induces an opposing current within the same windings. This results in a voltage drop across the component, allowing for power to be stored and then released at a later time, much like a battery.

The PM74SH-120M-RC is often used in circuits with high switching frequencies, such as DC/DC converters, for smoother control ramp-up. The inductor can also be used in automotive applications and in circuit designs which require high accuracy in controlling the current pulse width and frequency. Additionally, the low resistance of the PM74SH-120M-RC contributes to the overall efficiency of the circuit.

The main application field of the PM74SH-120M-RC is for high frequency switching applications in the automotive, power, and audio industries as well as other electronic equipment. The component is often used in power supplies and has been designed to satisfy the requirements of high frequency applications, offering a resistance of 0.20 Ohms, inductance of 120 uH and a maximum current of 1.1 Amps. It is also RoHS compliant and is manufactured using high quality materials to ensure its reliability and performance.

In summary, the PM74SH-120M-RC is an example of a fixed inductor designed and used for various high frequency switching applications. Its low resistance, high accuracy and durability make it a great choice for applications where current and voltage control are essential. The inductor is RoHS compliant, manufactured with high quality materials, and can be easily integrated into circuit designs.
