The USB-B-S-S-B-SM: Mounts surface-mount right-angle with solder termination; board guide and solder retention features aid alignment and reflow hold-down.
Within the Samtec USB-B series the USB-B-S-S-B-SM (Bulk) shares its 4-contact USB 2.0 Type-B layout, gold plating, and 1500-cycle durability with the tape-and-reel variant USB-B-S-S-B-SM-TR — the only difference is packaging. The through-hole sibling USB-B-S-S-B-TH replaces the board guide with a board lock for wave-solder retention; the USB-B-S-F-B-SM is a female jack version with the same SMT footprint and gold contacts.
