notes:
1) material designation will be a prefix for NiZn materials (ie.M-1098) or a suffix for MnZn materials
     (ie. BC-1098-M50)
2a) magnetic(inductance) tolerance +/-25% (for ui 7.5 - 5,000) and +/-30% (for ui> 5,000)
2b) magnetic(impedance) tolerance +/-20%
3) mechanical tolerances approximately +/-1.5% (nominal values may vary per material)
4) length adjustable to suit application requirements (given existing tool limitations)
5) call if required sizes not found (not all tool sizes are listed)
6) parts available coated with parylene (0.0005 in. nominal) (ie. BC-1098P-M50)
