note: most edges have full radius; suffix A designates different thickness from standard
notes:
1) material designation will be a prefix for NiZn materials (ie.RMX-500-7500) or a suffix for MnZn      materials (ie. SX-500-4000-M20)
2) magnetic tolerance for inductance +/-10% and for Q -20% (grading available for tighter tolerances)
3) mechanical tolerances approximately +/-5% (cross sectional), +/-2% (length) (nominal values may      vary per material) and straightness (or camber) is 0.011 in. per inch of length(0.050 max.)
4) parts are custom cut to length, insert length desired in p/n (ie. RMX-500-2500) to suit application      requirements
5) outer diameter may be ground to tighter tolerances (ie.+/- 0.002 in.), add suffix F
    (ie. RPX-375-3000F)
6) refer to Effective Permeability of Ferrite Rods for relationship between material permeability and rod      (effective) permeability
7) call if required sizes not found (not all tool sizes are listed)
8) silicone treatment (moisture proofing) available upon request, add suffix S (ie. RMX-1000-8000S)
