Fixed inductors are a type of inductor characterized by their fixed electrical properties. Typically, their inductance and current rating are fixed values that cannot be changed. The main purpose of a fixed inductor is to store energy in a magnetic field for use later. Inductors can also be used to reduce current ripple and other electrical disturbances or to filter out unwanted frequencies from an electrical signal. There are a variety of types of fixed inductors available, each with its own applications and working principles.

4445R-25K is a fixed inductor that has a number of important features. It has a 25 ohm rated input impedance that makes it suitable for wide-band operation. The inductance range is approximately 44.45 µH and the operating temperature range is-40 to +105 °C. This makes it suitable for harsh environment applications, such as in power supplies and automotive electronics.

The main working principle of the 4445R-25K is the generation of a constant magnetic field in response to an external current. This is accomplished by using two coils in the inductor, one acting as the primary coil and the other as the secondary coil. When an external current is applied, a change in the magnetic flux between the two coils produces a voltage across the secondary coil that acts to resist the change in flux. The voltage generated is proportional to the strength of the magnetic field and the rate of the current change.

The 4445R-25K is available in a variety of case styles and can be used in many different applications. It can be used in switched power supplies, DC-DC converters, AC-DC converters, common-mode filters, common-mode chokes, RF power amplifiers, and other applications where high current or low resistance is required. It is also suitable for use in power supply noise suppression as well as in noise-sensitive video, audio, and telecommunication applications.

The 4445R-25K is a very reliable and cost effective fixed inductor that is well suited for many applications. Its robust construction and wide operating temperature range make it an ideal choice for use in rugged applications and harsh environments. With its high current rating and low resistance, it is an ideal solution for reducing noise and power supply ripple.
