Ring terminal for 20 AWG, #4 stud
The 1577622-1 is a PIDG, Strato-Therm ring terminal from TE Connectivity AMP Connectors, accepting 20 AWG wire and terminating to a #4 stud. The terminal uses a nickel-plated copper contact with serrated termination for secure crimp retention, and the PEEK insulation is rated for a wire insulation diameter of 0.045" ~ 0.080" (1.14mm ~ 2.03mm).
Wire gauge and stud fit
The 20 AWG wire gauge and #4 stud size define the application range for this ring terminal. The serrated termination inside the barrel grips the conductor during crimping, reducing pull-out risk. The PEEK insulation withstands higher operating temperatures than standard nylon or vinyl, and the overall length of 0.833" (21.16mm) with an outer width of 0.281" (7.14mm) fits standard terminal blocks and studs.
