SM02B-SRSS-TB(LF)(SN)
JST
Common 2-pin JST SM series connector used for compact wire/board and module links.

Overview
The SM02B-SRSS-TB(LF)(SN) is a 2-position, side-entry (right-angle) surface mount header belonging to the JST SH series. This ultra-compact wire-to-board connector features a 1.0mm pitch, making it suitable for high-density electronic assemblies where PCB space is at a premium. It is fully shrouded to prevent incorrect mating and provides a secure friction-lock connection for low-voltage signal applications.
Why Choose This Part
The 1.0mm pitch design significantly reduces the footprint compared to standard 2.0mm or 2.54mm connectors. Its right-angle, side-entry configuration allows for lower profile assemblies, while the solder tabs (solder nails) provide robust mechanical strain relief for the SMT pads during cable insertion and removal.
Applications
Internal Battery Connections
Commonly used for connecting small LiPo or coin cell battery packs to PCBs in portable electronics.
Sensor Interface
Ideal for linking peripheral sensors to a main controller board in compact IoT devices.
Display Backlight Power
Used to provide power or control signals to small LCD and OLED modules.
Fan and Motor Headers
Small enough to serve as a power header for miniature 5V or 12V DC fans in enclosure cooling.
