HES SERIES
150 WATT
Powering Communications and Technology
DESCRIPTION
HES single output DC/DC converters provide up to
150 Watts of output power in an industry standard,
half-brick package and footprint. These units feature
ultra-high efficiency, Class A conducted noise specs,
and fixed switching frequency. The HES is designed
with open-frame packaging, along with planar
magnetics to provide maximum useable power with
minimal thermal constraints. The HES is especially
suited to harsh 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,
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.
