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.

Thickness (mm)

Plate thickness along the poling axis.

Estimate the thickness-mode fundamental resonant frequency of a piezoelectric plate using the documented 2860 kHz·mm k33 constant (frequency in kHz equals 2860 divided by thickness in mm). 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]

Resonant frequency (kHz)

Fundamental thickness-mode resonant frequency.

• Piezoelectric charge, voltage, displacement, sensitivity, and resonance depend on material constants, axis, geometry, preload, boundary conditions, frequency, temperature, dielectric loss, amplifier input, and hysteresis. Static measurements are limited by leakage.
• 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.

• PLL Lock Time

  Estimate the settling time of a phase-locked loop using the documented rule that lock takes roughly four time constants of the natural frequency in radians per second (4 divided by two pi times the loop bandwidth in Hz).

• Bandwidth From Q

  Calculate the bandwidth of a resonant circuit from its resonant frequency and quality factor.

• Charging Time Hours

  Estimate the hours needed to fully charge a battery at a constant current, including a documented 1.2 inefficiency factor that accounts for taper and losses.
