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

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)
