2150-18F

Inductors are electronic components which resistance to changes in electric current. Specifically, this resistance is to changes in the rate of current and not absolute current. Inductors are frequently used in applications where an energy store is desired such as in computing, communications and embedded systems. In this article, we will focus on the specifics of the 2150-18F fixed inductor and its power applications.

Operation and Working Principle

Fixed inductors have a fixed inductance value and are commonly used to pass current of a given frequency such as radio or television signals. This is done by creating a magnetic field around their specific winding; the strength of this magnetic field is determined by the inductance and is given in Henrys for rate of current. The 2150-18F is a linear inductor model with an inductance of 0.47µH ± 20% and a DC resistance of 4.6ohms.

When AC or DC current is passed through the inductor the result is a variable magnetic field. If the input frequency is below the self-resonant frequency of the 2150-18F it will attenuate current. This is opposed to the Overdriving effect of passing a higher frequency than the self-resonant frequency and will lead to an increase in current gain and saturation of the magnetic force.

Common Applications

The 2150-18F has a variety of applications including but not limited to:

• RF signal circuits for radio and TV
• Voltage Regulation circuits
• Inductor-Capacitor (LC) Circuits
• DC/DC converter circuits
• Radio Transmitters/Amplifiers
• Line Filters

The inductor is also widely used in switching power supplies and current/voltage sensing circuits. It can also be used to create ‘tuned’ amplifiers as well as being used in circuits which require high voltage withstanding.

In its simplest application the 2150-18F can be used as an impedance matching device in order to reduce noise or limit the current. Furthermore, as a variable reactive component, it can be used to adjust the phase angle or broaden the passband of an AC filter.

Conclusion

The 2150-18F fixed inductor is a versatile electronic component which has a variety of uses in both power and signal applications. It is highly efficient and designed with minimal impedance loss ensuring it can out-perform other inductors of this type.
