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.

† 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.
