Foil Crimp Area and Terminal Fit
The 276959-2 is a ring terminal from the Termi-Foil series, designed to terminate a foil conductor — not a round wire. The foil crimp area measures 0.454" x 0.454" (11.53mm x 11.53mm), which defines the rectangular pocket that accepts the foil tab. If your foil tab is smaller or larger than that square, this terminal will not crimp correctly. The ring terminal type mates with a stud or busbar, giving a permanent, vibration-resistant connection.
Sourced through independent distribution channels.
Termination and Tooling
This is a crimp-style terminal for foil — not a standard wire crimp. The foil crimp area is a square pocket, so the applicator or hand tool must match that geometry. If your shop already runs Termi-Foil tooling, this terminal likely feeds the same press; if not, factor in a tooling check before committing to the BOM line.
