How Steinmetz Core Loss works
Compute Steinmetz core loss in mW/cm^3 as k x f^alpha x (B/1000)^beta; defaults k = 0.001, alpha = 1.5, beta = 2.2. 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
- Core loss (mW/cm³)
- The resulting core loss returned as a number.
Limitations and assumptions
- 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.
Alternative or Complementary approaches
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.

- Inductor Steinmetz Core Loss Density
Estimate magnetic-core loss density with a fitted Steinmetz power law p=k f^α B^β. Units of k must match the selected frequency, peak flux-density, and desired output units; the model applies only over its fitted waveform/range.
- Core Area Product
Compute transformer core area product in cm^4 as (VA x 1e4) / (Kh x f x J x Kw x Bw); defaults Kh = 0.014, J = 400 A/cm^2, Kw = 0.4, Bw = 0.2 T.
- Common-Mode Choke Impedance
Estimate one winding's series RL impedance magnitude at frequency f as √[R²+(2πfL)²]. Enter the effective common-mode inductance and resistance at the operating point; real choke impedance also includes core loss, capacitance, and self-resonance.
