The NKE sub-miniature series of DC/CD Converters is
particularly suited to isolating and/or converting DC
power rails. A smaller package size,improved efficiency,
lower output ripple and 3kVDC isolation capability
through state of the art packaging and improved
technology. The galvanic isolation allows the device to
be configured to provide an isolated negative rail in
systems where only positive rails exist. The wide
temperature range guarantees startup from -40℃ and
full 1 watt output at 85℃.
