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.

LES SERIES - 15 WATT

LES DC/DC converters provide up to 15 watts of output power in

an industry-standard package and footprint. With a maximum

case temperature of 100°C, the LES is well suited for the most

demanding telecom, networking, and industrial applications. The

LES features 1500 VDC isolation, short circuit, and

overtemperature protection, as well as six-sided shielding. The

LES is available with optional enable and voltage trim pins. Please

see the IAD Series for dual output applications.
