The BXB50 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 BXB50 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 BXB50 series are approved to IEC950 by
UL, CSA and VDE.

Notes
1
Measured with 10 μF tantalum capacitor and 1 μF ceramic capacitor across
output.
2 di/dt = 0.1 A/1 μs, Vin = 48 Vdc, Tc = 25 °C, load change = 0.5 lo max. to 0.75 lo
max. and 0.75 lo max. to 0.5 lo max.
3 Units should be characterised within systems. External components required.
4 Input fusing is recommended based on surge current and maximum input
current.
5 This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.
6 Simulated source impedance of 12 μH. 12 μH inductor in series with +Vin.
7 Active high remote on/off option is available (standard product is active low),
designate with the suffix ‘FHT’ e.g. BXB50-48S05FHTJ. Consult factory for
further details and options.
8 Start-up into resistive load.
9 The ‘J’ suffix indicates that these parts are Pb-free (RoHS 6/6) compliant.
TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special
request, please contact your local sales representative for details.
10 NOTICE: Some models do not support all options. Please contact your local
