5-Pin 0.80mm Pitch SMT Right-Angle Header — JST SUR Series
The SM05B-SURS-TF(LF)(SN): Its defining footprint is the 0.80mm pitch, which sets the board routing density and dictates the mating half's contact spacing. Current rating is listed at 0.2A and 0.5A — this is a signal-level connector, not a power interconnect. The 30V voltage rating and tin-plated mating contacts suit low-current sensor lines, data signals, or control circuits in indoor equipment.
Solder Retention and Reflow Stability
Solder retention features are built into the header — these pads anchor the part to the PCB during reflow, reducing skew and tombstoning.
