Fixed inductors are electronic components which are designed to maintain a specific inductance, allowing current to flow through the inductor as it applies. The DR125-3R3-R is a particular fixed inductor manufactured by Coilcraft which is served for a wide range of applications.

The DR125-3R3-R fixed inductor provides engineers with a high-permeability, ferrite core material. This core material is what minimizes overall coil inductance. Additionally it offers low DC resistance which allows for an average current rating of up to 1.45A. Furthermore, the DR125-3R3-R offers a maximum resistance of 125 Ω, ohms, and a maximum inductance of 3.3µH, µhenries. The DR125-3R3-R can operate at ranges of temperatures from minus 40 to 85 percent centigrade, which ensures a long operating life.

The components are packaged in an epoxy-molded, plastic, case which measures 6.2mm, 0.24in, in length with a 8.5mm, 0.33in, width. The DR125-3R3-R inductor requires minimal space within the circuit, thus it is an excellent choice for high-density applications. The molded plastic casing also ensures protection against wear and tear.

The DR125-3R3-R inductor is designed for a wide range of applications in the consumer, industrials, infrastructure, and automation industries. In consumer applications, inductors are used in RFID, digital cameras, hearing aids, medical instruments, and pocket calculators as a source of energy. Industrial applications include DC-to-DC converters, converter output inductors, switched-mode power supplies, and telecommunications. Furthermore, it can be used in infrastructure and automation as choke inductors, DC/DC bias choke inductors, and battery chargers.

As with many inductors, the working principle of the DR125-3R3-R inductor is based on Faraday’s law of induction. This law states that when a conductor moves in a magnetic field, an electromotive force (EMF) output is generated. When current flows through the coil within the inductor, it induces a magnetic field which in turn creates a new EMF, thus an opposition to the original current. This produces the inductance which is necessary for so many applications.

The DR125-3R3-R fixed inductor is an excellent choice for a variety of applications. With its ferrite core material and epoxy-molded plastic casing, this inductor provides engineers with a small and reliable means of inductance. For use in a range of industries, the DR125-3R3-R inductor offers a long operating life and high-performing resistance to current. As a result, this inductor will offer superior performance and will remain a viable choice for years to come.
