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.

General
MTBF predictions may vary slightly from model to model.
Specifications typically at 25°C, normal line, and full load, unless
otherwise 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.

Thermal Impedance
Note:
Thermal impedance data is dependent
on many environmental factors. The
exact thermal performance should be
validated for specific application.
