Multi-gap PQ-core design

This Multi-gap PQ-Core Design Tool simplifies complex magnetic component engineering directly in your web browser. By entering the ideal core dimensions, gap conditions, and materials, the platform instantly calculates precise core factors, magnetic properties, and essential physical parameters. This automated process eliminates manual calculations to accelerate your magnetic design workflow.

Input the core dimensions:

A	B	C	D	E	F	G	H	I

Input the multi-gap conditions:

1. Number of the central stick cores:

For symmetry concern, the number should be even.

2. The spacer thickness (mm):

3. The center gap G3 (mm):

Select the material grade:

Output the results:

Core factors:

C1 =

mm⁻¹

C2 =

mm⁻³

Effective core parameters:

Ae =

mm²

Le =

Ve =

mm³

Amin =

mm²

Magnetic properties:

μe =

AL =

nH/N²
