(0.230 in. ± 0.020 in.)
The MW010-Series Power Modules are encapsulated in non-
conductive cases measuring 50.8 mm long, 40.6 mm wide,
and 12.7 mm high (2.00 in. x 1.60 in. x 0.50 in.)
.
Description
The MW010A, B, C, BK, and CL Power Modules are
dc-dc converters that operate over an input voltage
range of 36 Vdc to 75 Vdc and provide precisely reg-
ulated dc outputs. The outputs are fully isolated from
the inputs, allowing versatile polarity configurations
and grounding connections. The modules have maxi-
mum power ratings of 10 W at a typical full-load effi-
ciency of 83% (80% for the MW010A).
The modules are encapsulated in nonconductive
cases that mount on PC boards. In a natural convec-
tion environment, the modules are rated to full load at
85 °C with no heat sinking or external filtering.
For applications requiring remote on/off, the
MW010A1, B1, C1, BK1, and CL1 Power Modules
are available. These modules are equivalent to the
previously described modules, except for the addition
of the remote on/off and associated terminal.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.

Fusing Considerations
CAUTION: This power module is not internally fused. An input line fuse must always be used.
This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone
operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fus-
ing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The
safety agencies require a normal-blow, dc fuse with a maximum rating of 5 A in series with the ungrounded input
lead (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy
and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufac-
turer’s data for further information.
