3 Pin JST Cable wire harness

1：What are the features of a 3 pin JST cable?

• Rated Current: Wide range, from low current of 700 mA to medium power levels of 3A, 7A, and even high current up to 20A.

• Rated Voltage: Common rated voltage is 250V AC/DC; some models can support up to 600V AC.

• Contact Resistance & Insulation Resistance: Excellent design. Contact resistance is typically ≤20 mΩ, insulation resistance ≥100 MΩ, ensuring stable signal transmission.

• Pin Pitch (Pitch): Wide variety. Common pitches include 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm, 2.54 mm, and 6.20 mm. Smaller pitch is better suited for high-density wiring.

• Wire Gauge (AWG): Supports multiple wire sizes, common range from #22 to #28 AWG to accommodate different current transmission requirements.

2：What are the advantages of 3 pin JST cables?

• Space-Saving: They have a compact, low-profile design that’s ideal for dense PCBs and small devices like wearables and drones.

• Design Flexibility: You can find them in various pitch sizes (from 1.0mm to 6.20mm), wire gauges (e.g., 22 to 28 AWG), and cable lengths, often with color-coded wires for easy identification

• Simple to Assemble: They’re a plug-and-play solution that’s easy to connect/disconnect, and open leads can be pre-stripped/tinned for quick soldering.

• Readily Available: As an industry standard, JST connectors are widely available, cost-effective, and trusted by engineers worldwide

3：What are the standards of the 3 pin JST cable?

• UL (Underwriters Laboratories): A key safety certification in North America, including UL 1581 for wires/cables and UL 94 V-0 for flammability. Recognized JST components are listed under files like E60389.

• RoHS (Restriction of Hazardous Substances): Mandatory in many markets, restricting hazardous substances like lead and mercury.

• Automotive Standards: For automotive applications, IATF 16949 (quality management) and ECE R-118 (material flammability) are essential.

• CE Marking: Required for many products sold within the European Economic Area (EEA).

• ISO 9001: An international standard for a robust Quality Management System (QMS)
