*1 Rated inductance tolerance :
P25%,
the inductance at current 0[A] indicates the reference value.
*2 The number of turns indicates the reference value. The specification 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.
