VITROHM offers a SMD-version (RWN), that was designed for automatic PCB-assembly with in
blister-tape.

The power rating for this type is limited by the max. temperature of the moulding material.
Overheating may cause carbonizing of the plastic, short circuit may occur.

This limits also the pulse handling capacity.
50A can be carried by the internal contacts, but energy must not exceed 625 mWs.

Design Notes for Serie  RWN

If power rating is not the main concern, i.e. current ranges below 5A, a current sensing device in a
standard resistor package may be suitable.
