Fixed inductors, such as the SD25-101-R, are passive, two terminal components used in electrical circuits to introduce inductance to the circuit. These inductors are manufactured to maintain a precise level of inductance and usually have electrical ratings representing their safe operating limits within an electric circuit. The SD25-101-R is a widely used variant of the fixed inductor which is available as an off-the-shelf solution for a variety of electronic applications.

The SD25-101-R has a small form factor and is ideal for use in breadboard prototyping and other restricted space designs. Constructed from enamel-coated copper wire, the SD25-101-R inductor provides superior shielding and insulation compared to other types of fixed inductor. It also features a low resistance leakage flux, which makes it particularly suitable for power applications. In addition, the SD25-101-R has a high current rating of up to 100 mA, making it suitable for use in a wide range of applications.

The working principle of a fixed inductor is based on the idea that when electric current runs through a coil of wire, a magnetic field is created around the coil. The voltage induced in the coil is proportional to the amount of current that is flowing through the coil. The strength of this induced voltage is determined by the amount of wire wrapped around the coil and the shape of the coil. Most fixed inductor coils are made of several turns of wire wrapped around a core or ferrite material.

When the electric current running through the coil increases, the magnetic field increases in strength. This, in turn, induces a greater voltage in the coil, which results in a larger magnetic field being created around the coil. This larger magnetic field opposes the flow of electric current, causing the inductance of the inductor to increase. The result of these changes is a greater voltage drop across the inductor than what was originally generated by the electric current.

The SD25-101-R fixed inductor has a low DC resistance of 0.05 Ohms and is rated for a maximum current of 100 mA. This makes it suitable for many different power applications, such as DC motor control, LED lighting, and SMPS power supplies. It also has a working temperature range of -40°C to +125°C and can be used in automotive, industrial, and consumer electronics applications. Furthermore, it is UL certified for safety, making it an ideal choice for many different applications.

In addition to its power applications, the SD25-101-R also has many uses in telecommunications applications. Fixed inductors are often used to create wideband impedance matching networks in communications systems. They are also often used in RF amplifiers to form UHF and VHF oscillators and as transformers in high speed logic circuits. Furthermore, they are used in radio frequency and microwave resonators to create filter networks and can be used in antenna designs to reduce noise levels.

The SD25-101-R is a widely used fixed inductor it is easily available in many different standard sizes and configurations. It is a reliable and versatile component for a variety of electronic applications and offers high performance in terms of low resistance, high power, and wideband impedance matching. With its UL certification and safety approval, the SD25-101-R is an excellent choice for many different uses in electronic designs.
