description
Designed to convert a wide input
voltage range into an isolated
regulated voltage, the
VWRBT1-SMT series is well
suited for providing board-mount
local supplies in a wide range of
applications, including mixed
analog/digital circuits, test &
measurement equip.,
process/machine controls,
datacom/telecom fields, etc...
