Detailed Information see
Application Notes chapter "MTBF"
The RI series has been specifically designed for applications where board space is at a premium since these 2 Watt
converters have only a slightly larger foot print than the RO series 1 Watt converters.
With efficiencies up to 87%, the full output power is available over the operating temperature range -40°C to +85°C and
the converters can be used in ambient temperatures of up to 100°C with derating. The wide selection of input voltage and
output voltage options plus an I/O-Isolation of 1kVDC as standard makes these converters suitable for many industrial
applications.
