TPET-W2 Series
DESCRIPTION 0.25W 3KVDC Isolated Single Output SMD 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.
