*1 The inductance at current 0 [A]
indicates the reference value.
*2 The number of turns indicates
the reference value. The specifi-
cation of the inductance takes
precedence over that of the
number of turns.
The coils of the lying type are also provided
for all the items listed in the table above.
For a coil of the type, symbol E should be
added to the end of the part number shown
in the table (e.g. BM05201X7E).
The coils of the pedestal attachment type
are also provided for the items with symbol
@
in the table above. For a coil of the type,
symbol D should be added to the end of
the part number shown in the table (e.g.
BM05201X7D).
The items preceded by symbol
include
two types, or the depth type with pedestal
and the bed type with pedestal. To order
the item of the depth or bed type, add D or
B at the end of the item of the item name
respectively, as shown in the examples
below:(BM05201X7D for the depth type
with pedestal) (BM05201X7B for the bed
type with pedestal)
*Order the auxiliary pins separately if they
are required for the pedestal.
