Use this electronics calculation for a first-pass component, converter, signal, motor, or sensor estimate when the stated operating conditions and units match the device data.

Peak voltage (V)

Required number input.

RMS voltage (V)

Required number input.

Calculate the crest factor of a waveform from its peak and RMS voltages. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Crest factor

The resulting crest factor returned as a number.

• Compact electronics formulas omit some combination of tolerances, temperature drift, bandwidth, loading, parasitics, noise spectrum, nonlinearity, clipping, calibration, layout, and device-specific limits. Typical datasheet values are not guaranteed limits.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check the result against the current datasheet and worst-case operating corners, then verify the circuit or measurement with simulation and bench testing where failure matters.

• Peak From RMS

  Calculate the peak current of a sinusoid from its RMS current.

• RMS From Peak

  Calculate the RMS current of a sinusoid from its peak current.

• Average Rectified Voltage

  Calculate the average rectified voltage of a sinusoid from its peak voltage.
