The PA series provides a higher-current alternative to the PH series with a 3A rating, suitable for power delivery and signal applications. The secure locking mechanism prevents accidental disconnection from vibration or cable routing, while the insertion guide ensures easy and correct mating. The side-entry SMT configuration enables low-profile cable routing parallel to the PCB. The 250V voltage rating provides ample margin for most low-voltage and some line-voltage applications.","working_principle":"The SM03B-PASS-TBT(LF)(SN) operates as part of the PA SMT connector system. The surface-mount version uses a solder attachment to the PCB, with the side-entry orientation applying insertion forces parallel to the board surface, reducing peel stress on solder joints. The secure lock ramp on the header engages with the BAP-03V-1 housing. The 3A rating is supported by the robust phosphor bronze contact design with tin plating, maintaining contact resistance below 10m\u03a9 initially. The TBT tape and reel packaging enables automated pick-and-place assembly.","pin_description":"
