The 1 A current rating is per contact, but in a USB 2.0 application the VBUS pin carries the load while the other three handle data and ground — so the real limit is the VBUS contact at 1 A. ## Shielding and Board Locks — What They Do for the Build The copper alloy shield wraps the receptacle body and mates with the cable plug's shell to contain EMI. The shield is soldered to ground traces on the PCB through the through-hole tails. ## How the 61729-1010RLF Differs from Its Siblings The 61729-1010BLF is electrically and mechanically identical — same 4 contacts, same 1 A rating, same gold GXT plating, same board locks and shielding — but ships in a Tube instead of Tape & Reel. If your assembly line feeds from a tube magazine, the 61729-1010BLF is the one to order; if you run pick-and-place with a tape feeder, the 61729-1010RLF is the correct reeled variant. The 61729-1011BLF drops the GXT plating for standard gold finish — fine for occasional mating, but the cycle life will be lower than the 1500 cycles the GXT version guarantees.","metaTitle":"Amphenol FCI 61729-1010RLF USB 2.0 Type-B Receptacle, 1A","metaDescription":"Amphenol FCI 61729-1010RLF USB-B receptacle, 4 contacts, 1A, USB 2.0, shielded, board locks, RoHS.
