Listed in ascending order of "A" dimension
The "H" column gives for each bead size the calculated dc bias field in oersted for 1 turn and 1 ampere direct current.
The actual dc H field in the application is this value of "H" times the actual NI (ampere - turn) product.
Dimensions in bold type are in millimeters, italic numbers are nominal in inches.
