I understand that the force on a pendulem has two components: mv^2/r=T-mgcos, and then mgsin tangentially. Is the centripetal force constant for a pendulem?

No. Constant centripetal force would require a uniform velocity like a ball on a string spinning in a horizontal orbit.
Wiki animation of net force. If theta approached 90 degrees then tension would approach zero and tension is what is providing the centripetal force.
