摘要： A multilayered capacitor (10) has a dielectric block (12) with a marked position where the adjustable capacitance is to be placed. The capacitor has two end walls (18, 20) on which are first and second terminal electrodes (26, 28). The electrodes have first and second narrow bands (32, 33) extending over marginal end portions of first and second side walls (14, 16) of the block (12). Two narrow spaced conductive stripes (34) on the first side wall terminate short of the second band (33) to define a first rectangular U-shaped extension of the first terminal electrode (26) on the first side wall (14). In the block (12) are embedded spaced electrodes (52, 54) to determine the capacitance of the capacitor. A first stripe (38) of conductive ink of any desired width can be applied to an uncovered area of the first wall (14) to contact the U-shaped extension of the first terminal electrode (26) to adjust capacitance of the capacitor. Two other conductive stripes (36) applied to the second sidewall (16) to extend from the second band (33) and terminate short of the first band to define a second U-shaped extension of the second terminal electrode. A second stripe (42) of conductive ink can be applied to an uncovered area of the second wall (16) to contact the second U-shaped electrode extension to further adjust the capacitance of the capacitor.

摘要： Thick film capacitors with screened electrodes can not be laser trimmed without damage to the dielectric. To solve this problem a thick film capacitor, with a first electrode (12), at least one dielectric layer formed from paste (14, 16) and a thin second electrode (18) are formed on a substrate (10). The second electrode (18) is formed from an organo-metallic paste including gold atoms which electrode has a thickness of about 1 micron. This thin electrode (18) can be trimmed by a low energy laser beam (20).

摘要： A capacitor element on a chip, e.g. a MMIC chip, comprises a main capacitance in parallel with a series configuration of trimming capacitors. The total capacitance in parallel with a series configuration of trimming capacitors. The total capacitance value of the parallel arrangement can be increased from its inherently minimum value by applying one or more laser pulses to one or more of the trimming capacitors, such that in each case a short-circuit is produced between the metallization layer to which the pulse is applied and the other metallization layer making up the trimming capacitor.

摘要： The passive component (1) has a first part (22) of a material with a first resistance value, which value can be lowered to a second value by laser trimming. The second value is at most one tenth of the first value and preferably less. Said material crystallizes in a laser trimming process, which locally heats the material to at least a transition temperature. Said material contains at least two different elements, which are preferably aluminum and germanium. The passive component (1) may be, for example, a resistor or a capacitor and may be part of a thin-film network of resistors, capacitors and/or inductors. In a resistor, it is preferred to have a second part (4) which contains a different resistance material with a resistance value lower than the first value and preferably higher than the second value.

摘要： A monolithic capacitor (101) whose capacitance can be varied by removing part of an electrode (106). The capacitor may comprise an end termination (105), coupled to a plurality of internal electrodes (103), which are disposed in a dielectric (102), and a top electrode (106) which is disposed on one side of the dielectric. If a part of the top electrode (106) is removed, the capacitance of the monolithic capacitor is changed, without an unacceptable change in 'Q'. The top electrode (106) may be disposed so that a part of it may be removed with an energy beam device, such as a laser or a particle beam (108).

摘要： A monolithic multilayer capacitor of known capacitance has a body with six external walls and a plurality of spaced electrodes (30 and 32 to 36) embedded in the body and spaced from a first one of the walls. Two spaced end walls have electrical terminations (22, 24) to which alternate electrodes are respectively connected. The electrode adjacent the first wall is spaced a first distance (D2) and the remaining electrodes are spaced apart a second distance (D3). One or more slits (36) in the first wall sever the first electrode adjacent to the wall leaving all the other electrodes intact and reducing the capacitor by predetermined amounts (W) depending on the location of the slits.

摘要： A capacitor comprises an electrically conductive cylinder, an electrically conductive or semi-conductive cylindrical shell or shell segment arranged concentrically around the electrically conductive cylinder, and a dielectric arranged between the electrically conductive cylinder and the electrically conductive or semi-conductive cylindrical shell or shell segment. The dielectric comprises a particulate composite including a matrix material having a non-zero (e.g. negative) thermal coefficient of relative permittivity and a particulate filler material blended with the matrix material, the particulate filler material having an opposite (e.g. positive thermal) coefficient of relative permittivity. The positive thermal coefficient of relative permittivity is thereby selected such that the capacitance value of the capacitor is constant within a stability margin over a predefined temperature interval.
