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.

Shared inductance (nH)

Required number input.

Current slew (A/ns)

Required number input.

Estimate ground-bounce voltage from shared inductance and current slew rate using V=L·di/dt. Enter inductance in nH and current slew in A/ns; the numerical product is volts. 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]

Bounce Voltage V

The resulting bounce voltage v returned as a number.

• PCB trace calculations depend on finished copper thickness, geometry, dielectric stack-up, temperature rise criterion, ambient, neighboring conductors, return path, frequency, surface finish, and fabrication tolerance. IPC equations are approximations, not a substitute for the board fabricator's stack-up or field solving.
• 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.

• Ferrite Core Area Product

  Estimate required ferrite core window-area × cross-section from the Magnetics design form WaAc=Pout·Dcma/(Kt·Bmax·f). Enter circular-mils-per-ampere current-density allowance, gauss, hertz, and the topology constant from the same design method; output is cm⁴.

• Opamp Short Circuit Power

  Estimate output-stage dissipation during an op-amp short to ground as supply-to-short voltage magnitude times the measured short-circuit current; this is not total device power.

• Battery Life Calculator

  Estimate battery runtime from rated charge capacity and constant load current: hours = mAh / mA. Real-world derating (Peukert effect, temperature, cutoff voltage) is not modeled.
