The SM04B-NSHSS-TB (LF)(SN): Rated 50 V and 1 A per circuit, it's a signal-level interconnect — think sensor inputs, low-power I/O, or control lines where you don't need the current headroom of a larger pitch.
Solder retention feet anchor the header during reflow and resist shear force from the cable strain after assembly.
Yes, it carries RoHS compliance — no conflict with EU or similar restricted-substance regulations.
That's a signal-level rating — adequate for sensor inputs, control lines, or low-power I/O, not for power distribution.
