Popular input and output voltages are available. 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°C and full 1 watt output at 85°C3. For full details go to www.murata-ps.com/rohs www.murata-ps.com/support V V mA % mV p-p Typ. Max. Typ.

Murata Power Solutions CRE1 series of DC-DC converters are all 100% production tested at their stated isolation voltage. This is 1kVDC for 1 second for C versions and 3kVDC for 1 second for 3C versions. A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?” The CRE1 series, through hole variants (excluding surface mount variants) have been recognised by Underwriters Laboratory for functional insulation, both input and output should normally be maintained within SELV limits i.e. less than 42.4V peak, or 60VDC. The isolation test voltage represents a measure of immunity to transient voltages and the part should never be use.
