Notes
MTBF predictions may vary slightly from model to model.
Industrial temp range available
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.
Units are water-washable and fully compatible with commercial spray or immersion
post wave-solder washing equipment.
OBD dual output DC/DC converters provide up to 25
Watts of output power in an industry standard package
and footprint. These units feature excellent efficiency,
six-sided shielding, and fixed switching frequency. With
100°C case operation, the OBD units are especially suited
to telecom, networking, and industrial applications.
These units are 100% surface-mount construction and
fully compatible with production board washing
processes.
