Frequency, in the context of electronic components, refers to the rate at which an alternating current or voltage changes direction per second. It is measured in Hertz (Hz), which represents one cycle per second. Frequency is a crucial parameter for various electronic components, such as capacitors, inductors, and resonators. It determines the component's ability to store or release energy, filter signals, and resonate at specific frequencies. Understanding the frequency characteristics of electronic components is essential for designing and optimizing electronic circuits.

Inductance is a property of an electrical conductor that opposes changes in current flow. It is measured in henrys (H) and is represented by the symbol L. Inductance is caused by the magnetic field generated by the current flowing through the conductor. When the current changes, the magnetic field also changes, which induces an electromotive force (EMF) in the conductor. This EMF opposes the change in current flow.

Length, in the context of electronic components, refers to the physical dimension of a component along its longest axis. It is typically measured in millimeters (mm) or inches (in). Length is a crucial parameter for determining the physical size and space requirements of a component on a printed circuit board (PCB) or other assembly. It also affects the component's electrical characteristics, such as inductance and capacitance, which can be influenced by the length of conductors or traces within the component.
