Murata Power Solutions MER1 DC-DC Converter, 9V dc/ 111mA Output, 10.8 → 13.2 V dc Input, 1W, Through Hole,

1 W dual output SIP7 unregulated DC to DC converters with standard industry pinout and efficiency rating of up to 89%. These SIP7 DC to DC converters have an improved regulation performance making them suitable for applications where a wide output voltage variation can not be tolerated. An ideal application for these DC to DC converters is the provision of local supplies on control system boards with the additional benefit of having 1kVDC galvanic isolation to reduce any switching noise.

The MER1 Series of converters are not internally fused so to meet the requirements of UL 60950 an anti-surge input line fuse should always be used with ratings as defined below.
MER1S05xxSC: 1A
MER1S12xxSC: 0.375A
MER1S15xxSC: 0.375A
MER1S24xxSC: 0.2A
MER1S48xxSC: 0.1A
All fuses should be UL approved and rated to at least the maximum allowable DC input voltage.
