SM03B-SRSS-TB(LF)(SN)
Category
The JST SM03B-SRSS-TB(LF)(SN) is a 3-pin surface mount connector with 1mm pitch, 1A/50V specifications, designed for industrial and automotive applications requiring reliable PCB connections. Its Tin-plated contacts and UL94V-0 rating enhance durability in harsh environments, while the right-angle variant improves PCB space utilization. Soldering must follow strict reflow profiles, and thermal management should leverage adjacent copper traces. The component excels in medical and automotive control systems but is limited to 3-pin configurations, with higher pricing compared to standard connectors.
