Fixed Inductors
An inductor, also called a coil, a choke, or a reactor, is an electrical component that resists changes in electric current. They are essentially made of wire wound together in the shape of a coil. A fixed inductor, the common type, has a fixed inductance value determined by the number of turns of wire, and the type of core material inside the winding. In contrast, a variable inductor comprises an adjustable part that can be changed to yield a range of inductance values.

The B82442T1394K050 is a type of fixed inductor from EPCOS, featuring an impressively low DC resistance with a 1µH ±20% inductance. This 85°C, 2.0mm × 1.0mm, 0.85mm high SMT component also features a 2.5mm μH ±15% inductance and has a rated current up to 241mA.

Application Field
The B82442T1394K050 is ideally suited for applications that require an even lower saturation current. In addition, its larger mass helps to provide higher screen attenuation than the other miniaturized, low-profile inductors. This makes it an ideal choice for narrowband and mobile telephone applications, such as cellular phones, pagers, and cordless telephones, which require reliable component performance.

This inductor is also suitable for higher frequency applications, such as RFID tags, smart cards, and various high-speed, high-frequency systems. Its relatively high thermal resistance degrees make it suitable for use in power supplies and voltage control circuits. In the automotive electronics sector, it provides reliable performance at high temperature levels, making it an ideal choice for various power supplies, AC/DC converters, and various converters required in cars.

Working Principle
Fixed inductor devices work by building up electricity at a very low frequency. This process involves the use of a winding, which creates a magnetic field when electricity flows through it. The stored energy of an inductor is in this magnetic field. When this magnetic field is interrupted by a sudden voltage, the inductor will discharge said stored energy. This process is known as inductance.

The B82442T1394K050 has an inductance of 1uH ±15%, which means that it typically has a capacitance of 1 microhenry. This indicates that it has a low resistance to an AC current, so it can be used in a variety of electronics applications. This inductor works best in low-frequency applications, such as AC-DC power conversion and mobile communications. As a result, it is often used in power supply systems, such as laptop computers, LED lightings, and mobile phones.

Conclusion
The B82442T1394K050 is an ideal choice for applications that require a miniaturized, low-profile inductor. This component is able to resist changes in electric current and has a fixed inductance value. It is an ideal choice for narrowband and mobile telephone applications, such as cellular phones, pagers, and cordless telephones as well as high-speed, high-frequency systems. It has a low resistance to an AC current and is able to resist high temperatures in automotive electronics. The B82442T1394K050 is an excellent choice for power supply systems, such as laptop computers, LED lightings, and mobile phones.
