Powder Core AL Inductance
Calculate inductance L=AL·N² from a core's inductance factor and turn count. AL and output use the same unit per turn squared; account for DC bias separately because effective permeability can fall.

How Powder Core AL Inductance works
Calculate inductance L=AL·N² from a core's inductance factor and turn count. AL and output use the same unit per turn squared; account for DC bias separately because effective permeability can fall. 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
- Inductance Nh
- The resulting inductance nh returned as a number.
Limitations and assumptions
- Inductor calculations depend on core material, air gap, turns, frequency, waveform, temperature, DC bias, copper resistance, skin and proximity effects, fringing, and saturation definition. Small-signal inductance and nominal current rating may not describe switching operation.
- 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.

Estimate inductance drift with a linear ppm/°C coefficient. Core permeability and DC-bias effects can be nonlinear; use a datasheet coefficient applicable to the temperature range.
- Ferrite Bead Insertion Loss
Estimate small-signal insertion loss for a ferrite bead in series with a resistive load from the bead's resistive and reactive impedance at the selected frequency. The source is assumed ideal; use datasheet impedance at frequency and account for DC-bias effects separately.
- FPGA Clock Jitter Allowance
Calculate remaining setup-time budget for combined clock jitter after clock period, clock-to-output, combinational path delay, setup time, and skew. Use worst-case values in the same time unit.
