1945R-19F is an iron core fixed inductor, with its full name being 1945 Series Fixed Core Power Inductor. This series of inductors come in polyolefin and ferrite core designs, which both have their advantages and drawbacks depending on a customer’s needs. With the 1945R-19F, the polyolefin core is used. As such, the 1945R-19F can be subjected to high temperatures and frequencies, thus making it a suitable choice for many applications.

The 1945R-19F offers a range of inductance values from 4.7 uH to 100 uH, while its DC resistance per winding ranges from 0.5 to 5.3 ohms. As such, it can be used in a range of applications that can benefit from these parameters. Additionally, its core type consists of Poly-Xmaterial, as well as its inductor coating consisting of Sealcon or Polyfix for optional automatic mounting and soldering processes.

Moving on, the actual application is as follows: the 1945R-19F can be used in a variety of applications, such as snubbers, power supplies, DC-DC converters, inverters, EMI filters, high-side power switches, resonant circuits, and others. Furthermore, it is also suitable for use in consumer electronic devices, solar inverters, automotive electronic systems, and various industrial applications.

Lastly, the 1945R-19F’s working principle is this: This type of fixed inductor operates by storing energy in a magnetic field, and more specifically, a core that is wound with a conductive wire. This core is then subjected to an input current, which creates a concentrated magnetic field. This magnetic field will store energy in it, and when the current falls, it will then induce an opposing EMF proportional to the change in the current. This induced EMF is what’s responsible for the generation of power.

To summarize, the 1945R-19F fixed inductor is an iron core fixed inductor with reliable parameters of inductance and DC resistance. This device has a wide application range, and it is suitable for use in snubbers, power supplies, DC-DC converters, inverters, EMI filters, high-side power switches, resonant circuits, consumer electronic devices, solar inverters, automotive electronic systems, and various industrial applications. It operates by storing energy in a magnetic field, which is then induced when the current changes, leading to the generation of power.
