Tape & Reel is an unmodified reel of continuous tape as received from a manufacturer. A length of empty tape at the beginning and end, known respectively as a leader and trailer, enables the use of automated assembly equipment. The tape is wound onto a plastic reel according to Electronics Industries Alliance (EIA) standards. Reel size, pitch, quantity, orientation and other detailed information is usually found toward the end of the part’s datasheet. Reels are packaged according to the ESD (ElectroStatic Discharge) and MSL (Moisture Sensitivity Level) protection requirements determined by the manufacturer.
