Esd Machine Model Current Calculator
Loss less LC machine-model firstcurrentpeakV√(C/L), not HBMV/1500ohmsor a waveform standard. Explicitly zero damping idealization; test fixture compliance external. Actual matched units/topology and independently established parameters; not a safe device/electrical design or verified manufacturer rating.
Description
A lossless LC discharge gives an ideal first current peak from charging voltage, capacitance and inductance.

How to use Esd Machine Model Current Calculator and how it works
- Prepare actualInitialChargingVoltageVolts, callerVerifiedMachineModelCapacitanceFarads, callerVerifiedLoopInductanceHenries, with the units, conventions and assumptions below.
- Enter the required fields and run Esd Machine Model Current Calculator.
- Read result.value using the output definitions below.
- Correct any rejected inputs and rerun; interpret the result within the stated model and its assumptions.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualInitialChargingVoltageVolts | Actual Initial Charging Voltage Volts. Use the units and matching context stated in the calculation below. | number | Required; nonnegative; finite; other constraints below |
| callerVerifiedMachineModelCapacitanceFarads | Caller Verified Machine Model Capacitance Farads. Use the units and matching context stated in the calculation below. | number | Required; strictly positive; finite; other constraints below |
| callerVerifiedLoopInductanceHenries | Caller Verified Loop Inductance Henries. Use the units and matching context stated in the calculation below. | number | Required; strictly positive; finite; other constraints below |
Supply nonnegative capacitor voltage in volts and positive capacitance in farads and inductance in henries. Return voltage*sqrt(capacitance/inductance) in amperes under a lossless LC peak-current model. Machine-model fixture resistance, waveform and device susceptibility are not modeled.
peakCurrentAmperes=voltage*sqrt(capacitance/inductance) Apply the input ordering, units and branch conditions stated above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the calculated or selected fields below. | object |
| result.value | Conditional signed or magnitude current in amperes under the tool's stated convention. | number |

}Limitations and assumptions
The calculation uses the supplied observations and model inputs. It does not collect measurements, select a reference population or coefficient, or establish that the model applies to the actual case. The stated branch conditions and output units remain part of the result.
All fields require explicit values. Unexpected fields, wrong types, nonfinite numbers and sparse arrays are rejected. Alignment, bounds and supported-token rules are explained above; extremely large inputs or nonfinite results can also fail. Input errors differ from successful false comparisons, unavailable-domain flags and empty match lists.
Alternative or Complementary methods
Use Pcb Via Inductance Calculator for a complementary operation: An isolated via partial-inductance estimate omits its return-path coupling.
Use Pcb Trace Inductance Per Length Calculator for a complementary operation: A trace partial inductance per length depends on a stated isolated long-conductor approximation.
