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) |
 |
