OET SERIES - TRIPLE OUTPUT, 25 WATT
DESCRIPTION
OET triple output DC/DC converters provide 25
Watts of output power in an industry standard
package. The OET series features excellent efficiency
and industry-leading power density. The OET features
open-frame packaging to provide maximum useable
power with minimal thermal constraints. These units
are 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.
