Hi,
I had a problem on a yacht, the remote control system failed so I disconnected a station which I thought could be the cause of the problem. After that the problem disappeared so I removed the control lever to repair it.
Inside I found a DC/DC from RECOM R05A05:
http://www.alldatasheet.es/datasheet-pdf/pdf/35378/RECOM/R05A05.html
As the problem on board was only happening sometimes I decided to replace this component and test, my experience showed me some of this intermittent failures comes from DC/DC.
I choosed this one, Murata NMH0505DC:
**broken link removed**
So my doubt comes when I was testing the component, without load any of them gives 5V, one gives 6,4V and the other 8V. I connected 100 ohm resistor as a load and they give 5,3V and 5,45V. Are they manufactured for a specific load to have at its output the exact +5V and -5V?
The original one is for +100mA and-100mA output and the one I bought is for +200mA and -200mA output so I´m not sure if I should choose the same +100mA and -100mA.
