QES SERIES
66 WATT
DESCRIPTION
QES single output DC/DC converters provide up to 66
Watts of output power in an industry standard, quarter-
brick package. The QES converters feature open-frame
packaging, along with planar magnetics and a high
efficiency topology to provide maximum useable power
with minimal thermal constraints. The QES is suited to
telecom, networking, and industrial applications, and is
fully compatible with production board washing processes.

Notes
† MTBF predictions may vary slightly from model to model.
Specifications typically at 25°C, normal line, and full load,
unlessotherwise stated.
Soldering Conditions: I/O pins, 260°C, 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.
