S2B-PH-SM4-TB(LF)(SN)
Category
The JST S2B-PH-SM4-TB(LF)(SN) provides a compact, high-reliability 2-position surface mount connector suitable for automotive and industrial applications. Its tin-plated copper contacts and PA housing deliver 2A current handling with operating temperatures from -25°C to +85°C. The right-angle design enables space-efficient PCB layouts while maintaining UL94V-0 flammability. Proper thermal management through copper pad designs and controlled soldering profiles are critical for optimal performance. This connector is particularly advantageous in automotive control systems and medical devices requiring RoHS compliance and halogen-free materials, though its cost-effectiveness is balanced by specialized handling requirements and limited pin count flexibility.
