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.
IES DC/DC converters provide up to 20 watts of output
power in an industry-standard package. With 87%
efficiency and a maximum case temperature of 100°C, the
IES is well suited for the most demanding telecom,
networking, and industrial applications. The IES features
1500 VDC isolation, short circuit, and overtemperature
protection.
