notes:
1) material designation will be a prefix for NiZn materials (ie.H-665) or a suffix for MnZn materials
     (ie. SB-962-M20)
2) impedance values are calculated and are for reference only (actual values vary per application)
3) magnetic (impedance: ohms/single turn) tolerance +/-20%
4) mechanical tolerances approximately +/-1.5% (nominal values may vary per material)
5) length adjustable to suit application requirements (given existing tool limitations)
6) call if required sizes not found (not all tool sizes are listed), also see Toroids
7) parts available coated with parylene (0.0005 in. nominal) (ie. H-1026P)
