Overview
This datasheet provides detailed information on a series of dis-connectable crimp style connectors with a 2.0mm pitch, which JST manufactures. Designed for high-density internal wire-to-board connections, these connectors are both compact and cost-effective while offering a reliable connection solution.
Electrical Specifications
The connectors are rated for a current of 2A AC or DC, using an AWG #24 gauge wire, and a voltage rating of 100V AC or DC. They handle a temperature range of -25°C to +85°C, factoring in the temperature rise from electrical current application. Initial contact resistance is specified at a maximum of 10mΩ, and after environmental testing, it should not exceed 20mΩ. Insulation resistance is above 1000MΩ min., and they can withstand a voltage of 800V AC for one minute.
Physical Specifications
The connectors are characterized by their low profile—8mm in height once mounted and 4.5mm in width, promoting space conservation in various applications. Applicable wire gauges range between AWG #32 and #24, and they can be used with printed circuit boards (PCBs) 0.8 to 1.6mm thick.
Variants and Design Attributes
Several types of these connectors are available:
Surface Mount Model (SMT): This variant is designed for top or side entry and is viewed from the component side during assembly.
Through-Hole Type: Viewed from the soldering side, this type also supports top or side entry.
Quality Compliance and Usage Guidelines
These connectors are compliant with RoHS2 directives and are recognized under standards E60389 and R75087. They feature a fully shrouded header and a retention mechanism that secures them to the PCB. For the end-users’ accurate application, JST recommends consulting the “Handling Precaution for Terminal and Connector” available on their website. The company is also available for support on specifics not covered within the datasheet, such as hole dimensions for PC boards made of hard material, implying that customization or consultation might be necessary for some uses.
Conclusion
The connectors, which are robust in their contact reliability and variability in usage, are emphasized as standard components with non-cumulative tolerances (+0.05mm for all centers). The emphasis is on designing for high-performance expectations while ensuring environmental compliance and handling safety.
