The BXB100 Series are high power density dc-dc converters
packaged in the industry standard footprint (2.40 x 2.28 x 0.50
inches) to give designers optimum choices when specifying for
both new and replacement designs. Suitable for a wide range of
applications in nearly any industry, the BXB100 was particularly
designed with communication and distributed power applications
in mind. Using Bellcore 332, the MTBF is greater than 1,400,000
hours. Aluminum baseplate technology with four threaded M3
inserts makes heatsink attachment and optimum thermal
management easy. The BXB100 series are approved to IEC950 by
UL, CSA and VDE.
