Fixed inductors are passive electrical components that store energy in the form of a magnetic field. They help create a current when used in an AC circuit. As the name suggests, the inductance of a fixed inductor is not variable and they are made with a coil. These coils consist of wire that is wound around a magnetic material, such as ferrite. Fixed inductors are used to provide energy storage for resonant circuits, filter circuits, power supplies, and to control noise and interference.

A 1945-15F inductor is an ideal choice for many applications. It features a low-profile, open-frame design with a ferrite core. The 1945-15F is rated for operation in temperatures from -40°C to +85°C and is available in multiple configurations. The inductors feature high inductance, low DCR (DC resistance), and high current capabilities. Additionally, the 1945-15F features high Q-factor and temperature stability, allowing for improved efficiency and reliability in high-frequency applications.

The working principle of the 1945-15F is similar to that of any other inductor. It consists of a coil of wire wrapped around a core material, such as ferrite, which creates a magnetic field. When current passes through this magnetic field, a force is created which causes the inductor to store energy, inducing a voltage on its terminals that is proportional to the rate of change of current in the coil. This stored energy is then returned to the circuit, creating a current. This current opposes any sudden changes in the circuit, allowing the inductor to filter out any unwanted noise and interference.

The 1945-15F inductor is ideal for a variety of applications, including power supplies, low-frequency filtering, and resonant circuits. It has a low DCR and high inductance–making it a highly efficient and reliable component. Additionally, its high Q-factor and temperature stability make it an excellent choice for high-frequency applications. The 1945-15F is also a very cost-effective option, as it does not require additional components and is available in a range of configurations. The 1945-15F inductor is the perfect choice for any application where efficient energy storage and noise reduction are necessary.
