Description

The NKE sub-miniature series of DC-DC 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 of NKE0305S through state of the art packaging and improved technology. The galvanic isolation allows NKE0305S to be configured to provide an isolated negative rail in systems of  NKE0305S where only positive rails exist. The wide temperature range guarantees startup from 40°C and full 1 watt output at 85°C.
