BWR33W Datasheet, PDF (12/12 Pages) Murata Power Solutions Inc. – Regulated 3.3V and 5V outputs

Options and Adaptations
Optional Functions
The dual output BWR 33W DC/DC converters offer two mechanical options. Per
the Ordering Guide on page 2, the trailing DXX in each part number pertains to
the base part number. Part-number suffixes are added after the “DXX,” indicat-
ing the selection of standard options. The resulting part number is a “standard
product” and is available to any customer desiring that particular combination
of options, as described below.
Suffix Description
Blank On/Off Control function with positive polarity in pin 4 position. The
pin length is 0.2 inches (5.08 mm).
L1 Trim the pin length to 0.110 ±0.010 inches (2.79 ±0.25mm). This
option requires a minimum order quantity.
L2 Trim the pin length to 0.145 ±0.010 inches (3.68 ±0.25mm). This
option requires a minimum order quantity.
Adaptations
There are various additional configurations available on BWR 33W DC/DC’s.
Because designating each of them with a standard part-number suffix is
not always feasable, such are designated by DATEL in assigning a 5-digit
“adaptation code” after the part-number suffixes. Once a configuration has
been requested by a customer and created by DATEL, the resulting product is
available to any customer as a “standard” off-the-shelf product. Contact DATEL
directly if you are interested in your own set of options/adaptations. Our policy
for minimum order quantities may apply.
