The JST SIN-01T-1.8 is a single-circuit board-in crimp contact from the SIN connector series. Unlike a conventional wire-to-board housing system, the contact is first crimped to a wire, inserted directly into a PCB hole, and then soldered. This construction helps prevent solder from wicking into the conductor and is intended for permanent jumper-wire and external-circuit connections to printed circuit boards.
The exact SIN-01T-1.8 supports 0.13 to 0.5mm² wire, equivalent to AWG 26 to 20, with an insulation outside diameter of 1.2 to 2.5mm. Contact length is 10.0mm, with a secondary specified dimension of 3.55mm. It is intended for a 1.6mm PCB thickness and a 1.8mm +0.1/-0mm PCB hole.
The terminal is manufactured from brass with a tin-plated reflow-treated finish. In JST’s model-number system, “01” identifies the AWG 26 to 20 wire range, while “T” identifies the tin-plated surface finish.
The standard reel contains 7,000 contacts. The SIN series is specified for an operating-temperature range of -25°C to +85°C, including temperature rise caused by current flow. JST states that the current rating depends on the applicable wire, so a single fixed current rating should not be assigned to this part without application-specific confirmation.
The SIN series is RoHS2 compliant and is listed with UL Recognition E60389 and CSA Certification LR20812. The exact SIN-01T-1.8 remains listed in JST’s current official product database with downloadable engineering models and drawings.
