Fixed Inductors

Fixed inductors are vital components in electronics devices as they are widely used in radios and televisions, power supplies, high frequency amplification, telecommunications, and computers. These devices are designed to provide an electrical current at a known value and frequency for a particular application. One of the most popular types of fixed inductors is the HKQ04023N9C-E.

Application Field of HKQ04023N9C-E

The HKQ04023N9C-E is a high quality, low profile, fixed inductor designed for use in various high frequency applications. These inductors are specifically designed for low-frequency and medium-frequency applications, such as amplifier circuits, and are available in a wide variety of sizes and inductance values. Ideally, these inductors are suited to use in circuits where minimal power loss is desired such as power amplifiers, radio frequency amplifiers, switching regulator circuits, and digital signal processors.

Working Principle

The working principle of an inductor is based on Faraday\'s law, which states that a varying magnetic field inside a coil induces a voltage in the coil. An inductor is a form of an electric conductor, typically made of wire, and is used to store energy in the form of a magnetic field. In an induced-voltage setup, a changing current in the conductor creates a varying magnetic field, which in turn induces a voltage inside the conductor. When used in a circuit, the inductor increases the impedance of the signal, thus aiding in smoothing out the signal. Additionally, the inductor acts as a filter to remove any unwanted high frequency signals, and acts as a choke to reduce the chance of AC noise in the circuit.

Conclusion

The HKQ04023N9C-E is a high-performance, miniature size, fixed inductor that is ideal for low-frequency and medium-frequency applications. The working principle of an inductor is based on Faraday\'s law, which states that a current that changes in the conductor creates a magnetic field and induces a voltage in the conductor. This voltage can then be used to increase the impedance of a signal, filter out unwanted high frequency signals, and act as a choke to reduce the chance of AC noise in the circuit. The HKQ04023N9C-E is an ideal choice for applications that require a low-profile, low power-loss, and high quality fixed inductor.
