HOW TO ORDER
C R 4 14 34 EC XX Shape code Ferrite core material Used for all ferrite types Approximate length in mm Approximate width in mm Geometry code/gap code Special specification code
SHAPE CODE
0 – Standard C – Planar E core with clip recesses F – Planar E core option: no clip recesses
GEOMETRY CODE
EC – All E cores including ETD, EC, ER, EER, EFD, planar and lamination sizes IC – I cores
GAP CODE E CORE
I CORE
Note – Any practical gap available Cores are sold per piece (for sets multiply by 2). Gapped pieces are normally packed separately from ungapped pieces. If desired in sets, this must be specified.
