JST connector (Japan Solderless Terminal)

A JST connector is a small electrical connector widely used in electronics and lighting, including LED applications. The abbreviation JST stands for Japan Solderless Terminal , indicating that it is a solderless connection.

Features of JST connectors

  • Compact size : They are small and suitable for applications where space is limited.
  • Various pin configurations : They are available in 2-pin, 3-pin and more depending on the application.
  • Locking Mechanism : Many JST connectors have a click mechanism to prevent loosening.
  • Used for low voltage connections : Typically used for 5V, 12V or 24V LED strips, batteries and small electronic circuits.

Commonly used types of JST connectors

  • JST-SM (most common for LED lighting)
    • Suitable for LED strips and modules.
    • Often a 2-pin or 3-pin variant (for RGB strips).
    • Waterproof variants available.
  • JST-PH (small and compact)
    • Widely used for PCB connections in LED drivers and other electronics.
    • Pin spacing: 2.0 mm.
  • JST-XH
    • Popular in drones and battery packs.
    • Pin spacing: 2.5 mm.
  • JST-RCY
    • Widely used in RC (radio controlled) vehicles and batteries.

Where are JST connectors used?

  • LED strips and LED drivers
  • Battery connections in electronics and model building
  • Computer and printed circuit board (PCB) interconnections
  • Industrial and automotive applications

If you want to use a JST connector for a specific LED application, it's important to choose the correct pin configuration and size .
