TE Connectivity DIAMOND GRIP STRATO-THERM Heat Resistant Ring Tongue Crimp Terminals DIAMOND GRIP STRATO-THERM heat resistant ring tongue crimp terminals with insulation support for use where operating temperatures prevent standard insulated crimps being used. These DIAMOND GRIP STRATO-THERM heat resistant ring tongue crimp terminals are made from nickel plated electrolytic copper with a nickel silver sleeve and are designed to terminate solid and/or stranded conductors. When the terminal is crimped the wire inside is forced into the serrations or dimples of the barrel to maximise the electrical contact area after crimping. The maximum operating temperature for these DIAMOND GRIP STRATO-THERM heat resistant ring tongue crimp terminals is 343°C (650°F)
