AMORPHOUS CHOKE COIL
New!
(Reference sample)
W
D
: Maximum outer diameter
W : Maximum width
Total lead length (L)* : 30mm (+3mm, -3mm)
Soldering boundary (a)* : 0mm (+4mm, -0mm)
* The bottom of the core or coil ( )is defined as
D
a
the base surface.
The specification value of the soldering boundary a varies
L
depending on the number of windings of the wire
.
?MAJOR USES
@For switching mode power surpplies.
@For DC-DC converter.
?FEATURES
@Miniaturization in comparison with TM series coils.
@High inductance in low load current.
@For normal mode line filter.
@Low leakage flux due to gap-less structure.

*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)
