This is the SMT version of the popular B02B-PASK-1 through-hole power connector, with the added convenience of surface-mount assembly. The PA series secure lock prevents accidental disconnection of power connections, which is critical for 2-circuit power connectors that may be subject to cable pull forces. The TFT suffix indicates flip-type tape packaging, which presents the connector in the opposite orientation from standard TBT packaging for specific pick-and-place machine configurations. The 3A current rating handles typical low-voltage power delivery, while the 250V rating provides ample margin.","working_principle":"The BM02B-PASS-1-TFT(LF)(SN) operates as an SMT power connector in the PA series family. The surface-mount attachment uses solder joints to the PCB pads, with the top-entry orientation directing insertion forces perpendicular to the board surface. The secure lock mechanism engages with the BAP-02V-1 housing to prevent accidental disconnection. The TFT (flip tape) packaging is used when the pick-and-place machine requires the connector to be oriented with the contact side facing the carrier tape base, as opposed to the standard TBT orientation. This is typically needed when the connector height requires a specific nozzle approach angle.","pin_description":"
