DESCRIPTION 1W 3KVDC Isolated Single and Dual Output DC/DC Converters
Miniature surface mounted DC/DC Converters are an ideal and economical solution for many
applications where noise reduction, voltage isolation, voltage conversion in distributed power systems
is required. these converters are qualified for the higher temperatures requested by lead-free reflow
solder processes, especially for automated SMD production lines.
