Fixed inductors are devices which perform an important role in many electronic circuits by providing electrical energy storage in the form of a magnetic field. The 2727-02H is a fixed inductor which is designed to be used in a wide range of applications such as in switching mode power supplies, inverters, DC-DC converters, motor drives, and automotive power supplies.

The 2727-02H is a high-frequency attenuator type fixed inductor. It consists of three layers - a core, a windings and a shield, which exhibit characteristics that are a combination of inductance, capacitance and resistance. The core of the 2727-02H is made from permalloy, a high permeability material for high-frequency operation, while the windings are copper and the shield is ferrite.

The inductor\'s outer casing is made of flame-retardant plastic material (UL 94V-2) which provides protection against mechanical, electrical and environmental hazards. The 2727-02H is designed to operate at frequencies up to 200MHz and its self-resonant frequency (the frequency at which the inductor\'s reactance is equal to its resistance) is about 10GHz. The inductor is also designed to have an inductance stability of +/-2% at a constant frequency.

The working principle of the 2727-02H is based on Faraday\'s law. This law states that a voltage is induced in a coil when the magnetic flux through the turns of the coil changes. When a current is passed through the windings of the inductor, a magnetic field is produced around the turns of the coil, which causes a voltage to be induced across the terminals of the inductor due to the change in magnetic flux.

The 2727-02H is used in a variety of applications where high-frequency attenuation is required. It is commonly found in high-frequency power supply designs, such as DC-DC converters, inverters, motor drives, and automotive power supplies. Additionally, it can be used in low-frequency switching applications to reduce the impedance of an AC waveform.

In addition to its primary application as a high-frequency attenuator, the 2727-02H can also be used in other applications such as high-voltage snubber circuits, active filters, and signal filtering. By connecting two 2727-02H inductors in series, they can be used to reduce the power ripple at AC frequencies. As a result, the 2727-02H has a wide range of uses and is an important component in a variety of electronic designs.
