Notes:

Note4: add suffix “/SMD” for SMD version, or leave blank for DIP8 THT version.

The R2M is an isolated 2W DC/DC converter in a compact SMD package or DIP8 package

available with 4:1 inputs covering 5, 12, 24, and 48V rails providing single or dual regulated, short-circuit

protected outputs. There is no minimum load requirement. Isolation is 1.6kVDC/1min, and the

operating temperature is from -40°C up to +85°C without derating. Class A and Class

B EMC conformity requires only a few external components. Standard packaging is tube.
