Fixed Inductors

A fixed inductor, also known as a non-variable inductor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. It is also known as a choke or an air coil, as it is wound on a hollow core that is typically a ferrite shield or core, and the inductance of the component is fixed and unaffected by external parameters. Common uses include suppressing unwanted signals or providing additional filtering to reduce signal distortion and improve signal clarity korad.

It can also be used to create broadband matching networks, which are used to increase the performance of radio antennas and to improve signal sensitivity.

Working Principle

A fixed inductor works by creating a magnetic field when current passes through it. This generates a voltage (the back electromotive force) opposite to the supply voltage. This principle is known as Faraday\'s law of induction. This effect is used for a variety of functions, ranging from energy storage, filtering, and inductive heating to power regulation and isolation.

When current passes through the LQP02HQ0N9C02E, the core of the inductor produces a magnetic field and stores energy in the field. The inductor\'s flux trapped inside the core produces a constant inductance value, and this value is unaffected by external parameters like temperature, pressure, or humidity. The COTS construction ensures a low resistance, which is essential for creating filters that efficiently reject unwanted signals. The flux also provides a filtering effect that helps in improving signal clarity and minimizing noise interference.

The LQP02HQ0N9C02E also reduces the power losses due to its low impedance. This helps reduce the overall power consumption of the circuit. The superior suppression capability of the LQP02HQ0N9C02E ensures that it meets the needs of RF requirements where low energy loss is necessary.
