OBS SERIES - 25 WATT
DESCRIPTION
OBS single output DC/DC converters provide up to 25
Watts of output power in an industry standard package
and footprint. The OBS units feature excellent efficiency,
six-sided shielding, and fixed switching frequency. With
100°C case operation, the OBS converters are especially
suited to telecom, networking, and industrial
applications. These units are 100% surface-mount
construction and fully compatible with production board
washing processes.
