description

Designed to convert a wide input

voltage range into an isolated

regulated voltage, the

VWRBT2-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...
