JST connectors are electrical connectors manufactured to the design standards originally developed by J.S.T. Mfg. Co. (Japan Solderless Terminal). JST manufactures numerous series (families) and pitches (pin-to-pin distance) of connectors.Search by connector application; JST.

JST connectors are used in many types of products, and commonly used by electronics hobbyists and consumer products for rechargeable battery packs, battery balancers, battery eliminator circuits, 3D printers, and radio controlled servos."JST" connector confusion - the real story; rcgroups blog.

Sometimes the term "JST" is used generically to refer to any small white electrical connector mounted on printed circuit boards.

Connector series JST manufactures a large number of series (families) of connectors. The PCB (wire-to-board) connectors are available in top (vertical) or side (horizontal) entry, and through-hole or surface-mount.

Soldering A majority of JST through-hole headers can't withstand the temperatures required for reflow soldering, because the plastic has a lower melting point since they were designed for wave soldering methods. Some JST surface-mount headers are designed to handle higher temperatures of reflow soldering.JST through-hole soldering; Official JST blog.

Confusion on the Internet End-users and 3rd-party sellers on eBay often describe connectors by their wrong name thus perpetuating confusion of the exact series of a specific connector. It is very common in blogs and websites to incorrectly name a specific connector only by the name of the manufacturer.

To minimize confusion, it is best to describe a connector using: the manufacturer's name, exact connector series, and optionally the pitch, such as "JST-XH" or "JST-XH-2.50mm" or "2.50mm JST XH-series" or other variations.

The official J.S.T. Co. website allows users to check certain models for their authenticity and specifications.

Note: Some 2.50 mm parts are incorrectly sold on the Internet as , and the 1.25 mm parts as .
