LC Filter Calculator

About This Tool

The LC Filter Calculator is a handy tool for anyone working with inductor-capacitor filters. It helps users easily determine the cutoff frequency (fc) based on the values of inductance (L) and capacitance (C). Whether you're designing a low-pass, high-pass, or band-pass filter, this tool simplifies the process by providing instant, accurate calculations.

To use this calculator, input the inductance (L) with its preferred unit (Henry, milliHenry, or microHenry) and the capacitance (C) in Farads or its subunits (mF, μF). The tool automatically validates inputs to ensure they are positive numbers. As inputs are entered or adjusted, the cutoff frequency updates immediately using the formula: fc = 1 / (2π√(LC)). The result is displayed prominently in Hertz, formatted to two decimal places.

Designed for electrical engineers, electronics students, and hobbyists, this tool streamlines filter analysis and component selection. It supports desktop and mobile browsers with a clean, modern look, high contrast for accessibility, and responsive layout for ease of use. Optional features include unit conversion, calculation history, and export options for professional use or educational purposes.
