Introduction to Fixed Inductors

Fixed inductors are passive electrical components that store energy in an electromagnetic field when current passes through them. They are most commonly used for radio frequency filtering, signal coupling, impedance matching and power conversion from AC to DC. Fixed inductors are generally characterized by their inductance value, current rating, and other physical parameters such as maximum voltage, temperature rating, size and tolerance.

2674-04L Fixed Inductors

The 2674-04L fixed inductor is a compact space-saving device designed for high performance applications. It boasts a tolerance of +/-20% on inductance and excellent DC current ratings of up to 4.2A. It also has a compact size, with a diameter of just 4.5mm and a height of 6.5mm, which makes it ideal for use in tight spaces. In addition, it has a low DC resistance of just 0.135 ohms and a low DC current rating of 0.4A.

2674-04L Application Field and Working Principle

The 2674-04L fixed inductors are most commonly used for radio frequency filtering, signal coupling, impedance matching and power conversion from AC to DC. These inductors store energy in an electromagnetic field when current passes through them, thus providing isolation from external signals. As current passes through the inductor, the stored magnetic field also serves to limit the overall current flow and reduce voltage spikes.In radio frequency applications, the fixed inductors reduce the signal amplitude, preventing it from exceeding the input impedance. This is achieved by introducing a capacitive reactance that can be adjusted by changing the inductance of the inductor. In impedance matching applications, the inductor can provide a low resistance path to ground, allowing the impedance of the circuit to be adjusted to match the desired performance levels.In power conversion from AC to DC, the inductor acts as an energy storage device, allowing it to convert AC current into a more stable DC current. This provides a cleaner signal with less fluctuation than would be achieved if only a rectifier was used.

Conclusion

In conclusion, the 2674-04L fixed inductors are a highly efficient and reliable component for a variety of applications. With its low DC resistance and high current rating, it is ideal for applications where power conversion from AC to DC is required. It is also useful for impedance matching and radio frequency filtering applications. Its small size and high efficiency make it well-suited for use in tight spaces.
