SM04B-GHS-TB(LF)(SN)
Category
The JST SM04B-GHS-TB(LF)(SN) is a high-reliability surface mount connector designed for compact 4-pole wire-to-board connections in extreme environments. Its phosphor bronze contacts with tin plating provide excellent conductivity and durability (-25°C to +85°C operation), while the right-angle design saves PCB space. Ideal for automotive, industrial, and medical applications requiring small form factors and high durability, though it demands careful thermal management and soldering techniques. The connector's UL94V-0 flame rating and 50V/1A specifications make it suitable for harsh environments but requires larger order quantities compared to standard connectors.
