With five circuits in a single-row layout, this connector provides a versatile interface for signal and low-power connections. The SM4 4-pad SMT footprint ensures mechanical stability on the PCB, while the side-entry orientation enables cable routing along the PCB surface. The 2A current rating and 100V voltage rating make it suitable for USB interfaces, fan controls, and various signal routing applications.","working_principle":"The B5B-PH-SM4-TBT(LF)(SN) operates as part of the PH disconnectable crimp-style connector system. The header mates with the PHR-5 wire housing using SPH crimp contacts on 30-24 AWG wire. The SM4 footprint's additional solder pads resist the peel forces generated during cable insertion and extraction cycles, with up to 30 mating cycles specified. The insulation resistance of 1000M\u03a9 minimum and withstanding voltage of 800V AC\/minute ensure reliable electrical isolation between adjacent circuits even in high-humidity environments.","pin_description":"
