inductor stored energy calculator online

Use inductor stored energy calculator online for inductance H, current A. Constant linear inductance; magnetic saturation excluded. Ideal nominal component model. Verify topology, operating range, tolerances and ratings against the actual component datasheet.

How to use it

Enter inductance H. Set current A. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
inductance HMain input. Positive values. 0.01
current AOption. Signed finite values. 2

Calculation method

energy_J = 0.5*inductance_H*current_A^2 (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply inductor stored energy calculator to the case below, keeping the displayed units and assumptions. Constant linear inductance; magnetic saturation excluded.

Choose the right tool

Match the topology before entering values: series and parallel networks, inverting and noninverting stages, and buck and boost converters use different equations. Component ratings, parasitics, protection and measured conditions require separate review.

Limitations and common mistakes

  • Constant linear inductance; magnetic saturation excluded. Ideal nominal component model. Verify topology, operating range, tolerances and ratings against the actual component datasheet.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
