ABSTRACT:
A surface mountable, high current resistor (20) is formed generally in the shape of an inverted "U". The top portion (22) of the inverted "U" is flat and contains one or more openings (26, 27) that serve to alter the resistivity of the resistor. The openings are formed so as to be inverted mirror images of each other, thereby cancelling inductive effects introduced by the openings. The ends of the "U" are formed into two or more legs (24) that serve to provide stability and a mounting area for soldering the resistor to a printed circuit board. A flat, unbroken portion (28) in the center of the resistor serves as a convenient area to handle the resistor with a vacuum tool during printed circuit assembly.
