The TB suffix adds a positioning boss for PCB alignment, and the HF designation indicates high-frequency signal capability.","working_principle":"The JST LE series uses a crimp-contact-to-header mating system. The header has a built-in lock that engages with the mating housing to prevent accidental disconnection. The boss (TB) provides mechanical stability during SMT reflow. The HF variant uses materials and geometry optimized for minimal signal reflection at higher frequencies.","pin_description":"
