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.
