A non-polarized laser trim chip stub in accordance with the invention includes a trimmable top conductor ( 12 ) capable of being trimmed to alter the electrical properties of the chip stub, a bottom conductor ( 58 ) having at least a first conductive portion ( 68 ) and a second conductive portion ( 72 ), a dielectric ( 44 ) separating said top conductor from said bottom conductor, and conductive passages ( 42 ) electrically connecting the top conductor or a portion thereof to the bottom conductor or a portion thereof. In alternate embodiments, the non-polarized laser trim chip stub's top conductor ( 102 ) is separated into a trimmable stub portion ( 110 ) and an end portion ( 112 ), and the bottom conductor ( 150 ) may be separated into three conductive portions ( 160, 162 and 164 ) to allow for the middle portion ( 162 ) to be used as a heat sink to aid in the dissipation of heat generated during high power applications. |
