2727-20F

Fixed inductors refer to passive components mainly composed of winding, core and other materials, which play the role of AC inductance in the circuit. 2727-20F is one kind of fixed inductor with the application fields such as DC-DC conversion, RF signal filtering, and communications.

Specification of 2727-20F

2727-20F is an inductor with a 2827 (7.3 * 7.3 * 5.2mm) package. The primary technical indicators include rated current (Ir), inductance (L), resistance rate, maximum current limit (Imax) and rated current tolerance. The rated current of 2727-20F is 0.4A, the inductance is 22uH, the resistance is 86mΩ, the maximum current limit is 1.05A, and the rated current tolerance is 20% ±. It is worth mentioning that this inductor has a higher rated current than other 2827 type inductors such as 2727-10F and 2727-15F.

Application field of 2727-20F

2727-20F has broad application fields. It can be used for DC-DC conversion, RF signal filtering and communications,which can reduce interference, shield signals, block direct current, smooth voltage, store and release energy, and filter radio frequency signals. It can be used in various electronic products such as satellite receivers, TV antennas, radio frequency cameras and mobile phones. It is especially suitable for transmitting power amplifiers and low-frequency power supplies in satellite receivers.

Working Principle of 2727-20F

The working principle of 2727-20F can be understood by the classic "reel model" of inductors. Due to the presence of a coil inside the inductor, an inductance will be established when an alternating current flows through it, and energy will be accumulated in the coil. When the current direction is reversed, the coil will provide counter-electromotive force to reduce the current flowing through, and the stored energy will be released slowly in the form of current. Thus, by controlling the parameters of inductors such as inductance, it is possible to improve the quality of the signal, reduce interference, protect components, and anti-surge, so as to achieve the purpose of stabilizing the circuit.

Conclusion

In conclusion, 2727-20F can be classified as a fixed inductor, which has strong application fields such as DC-DC conversion, RF signal filtering and communications, and has high rated current tolerance. Its working principle can be described by the "reel model", which is to accumulate energy and release energy slowly. It can play a role in stabilizing circuit voltage, filtering RF signals and protecting the whole circuit.
