Abstract
An end terminated high power chip resistor-printed circuit board assembly (9) suitable for use in applications requiring miniature surface mount resistors capable of high power dissipation. An end terminated high power chip resistor (8) is constructed by coating a portion of the bottom of an end terminated chip resistor with a conductive plate (12). The end terminated high power chip resistor (8) is mounted to a printed circuit board having at least one via (23) lined with metal (20) wherein the conductive plate (12) is positioned above the via (23) lined with metal (20). A heat sink (16) is mounted to the printed circuit board opposite to the side to which the end terminated high power chip resistor (8) is mounted and is in contact with the metal (20) lining via (23).
