Micro USB Stand-Up Sticker with Rolled Edges

The Micro USB stand-up sticker with rolled edges is a vertical surface-mount receptacle variant distinguished by its rolled-edge shell design and stand-up mounting orientation. "Rolled edges" refers to the inward-curled or flanged geometry of the metal shell's rim, which serves both structural and functional purposes.

Design and Construction

This connector is a standard 5-pin Micro USB Type-B female receptacle designed for vertical (180°) SMT mounting on a PCB. The "sticker" designation indicates surface-mount technology (SMT), allowing the connector to be soldered directly onto the board surface without through-holes. The "stand-up" orientation means the mating face points perpendicular to the PCB, saving horizontal board space compared to right-angle variants.

The rolled edges feature is a mechanical refinement of the metal shell. Rather than leaving the shell rim as a sharp, flat edge, the metal is curled inward to form a smooth, rounded lip. This design provides several benefits: it improves the connector's structural rigidity, reduces the risk of sharp edges damaging the mating cable or the user's fingers, and can help guide the plug during insertion. Some datasheets describe this as a "flange" or "rolled mouth" design.

Technical Specifications

Typical specifications for this connector class include:

• Contact Count: 5 pins

• Mounting: Vertical SMT, with or without locating pegs

• Height Above Board: Commonly around 5.2 mm

• Rated Current: Up to 3 A

• Operating Temperature: -40°C to +85°C

• Mating Cycles: Up to 3,000 to 10,000 cycles, depending on manufacturer

• Materials: LCP housing (UL 94V-0), copper alloy terminals, stainless steel or copper alloy shell

• Packaging: Tape and reel

Applications

This connector type is widely used in power banks, Bluetooth speakers, portable chargers, car accessories, and compact consumer electronics where board space is limited and vertical entry is preferred. The rolled-edge shell adds durability in applications where the connector may face repeated insertion cycles or mechanical stress.
