Fixed inductors, also known as "choke coils" or "coil inductors," are passive electrical components consisting of a wire wound into a tightly packed coil of one or more turns. They are used to filter out or pass only specific frequencies or specific ranges of frequencies in an electric circuit. The 7447789212 is a fixed inductor specifically designed for RF applications.

Applications

Fixed inductors are widely used in a variety of electronic circuits. The 7447789212 is designed to provide high levels of filtering when working with RF signals. It is mainly used for RF filtering circuits such as mobile device antennas, WLAN antennas, and other RF devices. Its high Q factor, high inductance and low ESR qualities make it a viable option for these types of applications.

Features

The 7447789212 has several features that make it well-suited for RF applications. It has a high Q factor of 65 at 100 MHz, allowing it to filter out unwanted frequencies and signals, while still allowing desired signals to pass through. It also has high rated inductance (100nH to 50uH) and low DCR resistance (0.102 at 100 MHz). These features combine to make it suitable for a wide variety of RF applications.

Design and Construction

The 7447789212 is constructed using an air core inductor design. It has a shielded winding that helps reduce noise and interference, as well as a ferrite core that further helps reduce losses and increases the inductor\'s Q factor. The shielded winding ensures that there is no unwanted EM radiation, making it suitable for use in sensitive RF applications.

Working Principle

Fixed inductors work by creating a magnetic field around them when a current is applied. When alternating current is applied, the magnetic field expands and contracts as the current alternates. This can be used to alter the frequency of the current, filtering out high frequencies while allowing low frequencies to pass. This is done by varying the inductance of the circuit. This makes the 7447789212 an ideal component for filtering out unwanted signals while allowing desired signals to pass.

Conclusion

The 7447789212 is an ideal fixed inductor for RF applications. Its high Q factor, high inductance, and low DCR resistance make it a viable option for a variety of RF applications. It is constructed using a shielded winding with a ferrite core, which helps reduce losses and EM radiation. Its working principle is based on the principle of electromagnetic induction, using the magnetic field created by the current to filter out frequencies. This makes it an ideal component for filtering RF signals.
