Standing axial-leaded surface mount capacitor

摘要

A standing axial-leaded surface mount capacitor is formed of a dielectric chip capacitor sandwiched between first and second blocks. The end blocks have profiles to match the profile of said chip capacitor. The end blocks are conductive at least on their outer surfaces and serve as leads to attaching to metallic surface traces of a printed circuit. In one preferred embodiment, the end blocks are ceramic cubes with metallic surfaces on its faces. The metallized cubes give the device rotational symmetry about its long axis, so that the capacitor will have identical performance in any orientation. This feature makes it possible to automatically pick and place the device onto a circuit board. Preferably, the dielectric chip has a square profile of the same dimension as the ceramic cubes. The profile of the cubes and the chip can be 20 to 25 mils to match the width of a typical printed circuit trace. The capacitors can be of any typical value, i.e., between 0.05 and 300 pf.
