Abstract
The utility model discloses a novel chip resistor comprising a substrate, an upper surface electrode and a lower surface electrode, wherein the length of the substrate is larger than or equal to 4.2mm and smaller than 6.3mm; the width of the substrate is larger than or equal to 2.5mm and smaller than 3.2mm; the thickness of the substrate is larger than 0.55mm and smaller than or equal to 1.05mm; the upper surface electrode and the lower surface electrode are respectively arranged on the upper surface and lower surface of the substrate; the upper surface electrode is connected with the lower surface electrode through an end electrode; and the upper surface of the substrate is provided with a protective layer. The length and width of the resistor are reduced, and meanwhile, the thickness of the resistor is increased, so that the mounting space is saved, in addition, the rated power of the resistor is kept at 1W, and meanwhile, the temperature coefficient of the novel chip resistor is reduced to 100PPM from the power 300PPM of the traditional chip resistor.
Description
Technical field
The utility model relates to a kind of resistor, and concrete is a kind of novel chip resistor.
Background technology
It is little, in light weight that chip resistor has a volume.Can high-density installation, the reliability height.The characteristics that weldability is good.
Along with the development in high tech electron fields such as communication, computer, Aeronautics and Astronautics, chip resistor is used also more and more widely owing to the characteristic superiority of self.Usually chip resistor all because size is little, can effectively save assembly space, but common power is all lower, how to make chip resistor accomplish small size, and power is greatly a problem of present chip resistor development.Along with radio complete machine, instrument develop to high frequency, little frequency field, in order to adapt to its development, the power-type plate resistor will become a kind of demand of its development, therefore need a kind of novel resistor of design, both dwindled volume, do not reduced power again, satisfied the demands.
The utility model content
The utility model proposes a kind of novel chip resistor, both dwindled volume, do not reduce power again.
The technical solution of the utility model is achieved in that a kind of novel chip resistor, comprises substrate, upper surface electrode and lower surface electrode, and the length of described substrate is more than or equal to 4.2mm and less than 6.3mm; Width is more than or equal to 2.5mm and less than 3.2mm; Thickness is greater than 0.55mm and smaller or equal to 1.05mm; Described upper surface electrode and lower surface electrode are located at the upper and lower surface of substrate respectively, and upper surface electrode links to each other by termination electrode with lower surface electrode, and substrate upper surface is provided with protective layer.
Further, the length of described substrate is 4.2mm, and wide is 2.5mm, and height is 1.05mm.
Further, described substrate is a ceramic substrate.
Further, described protective layer is the glass glaze protective layer.
The beneficial effects of the utility model are: reduce the resistor length and width, increased the thickness of resistor simultaneously, when saving installing space, and guarantee that the rated power of resistor is 1W, the simultaneous temperature coefficient drops to 100PPM by the 300PPM of traditional chip resistor.
