HBS DC/DC converters provide up to 50 Watts of
output power in an industry standard half-brick footprint.
The HBS units feature excellent efficiency, Class A
conducted noise specs, and fixed switching frequency.
The HBS, using open-frame packaging, along with planar
magnetics provides maximum useable power with
minimal thermal constraints. The HBS series is
especially suited to telecom, networking, and industrial
applications.

Notes
MTBF predictions may vary slightly from model to model.
Specifications typically at 25C, normal line, and full load, unless otherwise
stated.
Soldering Conditions: I/O pins, 260C, ten seconds; fully compatible with
commercial wave-soldering equipment.
Safety: Agency approvals may vary from model to model. Please consult factory
for specific model information.
Units are water-washable and fully compatible with commercial spray or
immersion post wave-solder washing equipment.
