Note:1) The part numbers indicated in the above table are for products with a brazed seam. 
2) *The crimping will be more secure if the total cross-sectional area of the wire is at least 0.5 mm2.
Examples: If the cross-sectional area of the wire is 0.3mm2, fold the wire in two when crimping the terminal. 
If the cross-sectional area of the wire is 0.5mm2, crimp the terminal onto the wire as it is.
3) Delivery lead times may vary depending on the product. Contact JST for details.
