It withstands temperatures of -40 to 221 degrees F (-40 to 105 degrees C). Its durable brass construction offers good conductivity and a tin-plated finish resists corrosion.3M Color-Coded Standard Female Disconnect Terminal attaches to the mating part with a tongue that slips over the male tab. This terminal has a butted-seam barrel which is covered by a funnel-designed, rigid-molded, polyvinyl chloride sleeve.
