    摘要: An inexpensive fine resistor which do not require dimensional classifications of discrete substrates, eliminating a process of replacing a mask according to a dimensional ranking of each discrete substrate as in the prior art. The resistor includes discrete substrate (11) made into pieces by dividing an insulated substrate sheet along a first slit dividing portion and a second dividing portion perpendicular to the first dividing portion; top electrode layer (12) formed on a top face of discrete substrate (11); resistor layer (13) formed such that a part of resistor layer (13) overlaps top electrode layer (12); protective layers (14, 16) formed so as to cover resistor layer (13); side electrode layer (17) formed on a side face of discrete substrate (11) such that side electrode layer is electrically coupled to top electrode layer (12).

    摘要: Disclosed is a thin film chip resistor having a structure suitable for effectively utilizing a slit substrate and simplifying a thin film forming step, in which thick film electrodes are formed on upper and lower surfaces of an insulator substrate, the thin film resistive layer is formed between thick film electrodes, and thin film electrodes connected to the thin film resistive layer are formed on both side portions of the upper surface of the insulator substrate. Furthermore, provided is a method for fabricating the thin film chip resistor, which can omit the step of forming thin film on a lower surface of the insulator substrate and minimize a defective proportion, which may occur during parting the insulator substrate along slits, by securing a space sufficient for contacting to probes with electrodes in a laser trimming step.

    摘要: Thermistor chips are produced by preparing ceramic green sheets, applying an inorganic material such as a glass paste on these green sheets in areas including lines along which they are to be later cut, stacking a plurality of these green sheets one on top of another to obtain a stacked body, obtaining chips by cutting this stacked body along those pre-specified lines and subjecting these chips to a firing process to obtain sintered bodies, and forming outer electrodes on mutually opposite end surfaces of these sintered bodies. A thermistor chip thus produced has a thermistor element having outer electrodes on its mutually opposite end surfaces, and diffused layers of an inorganic material having a higher specific resistance than material of the thermistor element. These diffused layers are formed proximally to externally exposed surfaces of the thermistor element.

    摘要: A chip resistor includes an insulating substrate 11, top terminal electrodes 12 formed on top surface of the substrate using silver-based cermet, bottom electrodes 13, resistive element 14 that is situated between the top terminal electrodes 12 and overlaps them partially, an optional internal protective coating 15 that covers resistive element 14 completely or partially, an external protective coating 16 that covers completely the internal protection coating 15 and partially covers top terminal electrodes 12, a plated layer of nickel 17 that covers face sides of the substrate, top 12 and bottom 13 electrodes, and overlaps partially external protective coating 16, finishing plated layer 18 that covers nickel layer 17. The overlap of nickel layer 17 and external protective layer 16 possesses a sealing property because of metallization of the edges of external protective layer 16 prior to the nickel plating process.
