Abstract

The invention discloses a chip resistor. The resistor comprises a substrate, an electrode, a resistor body and a protective layer, wherein two electrodes are symmetrically arranged on the substrate; aresistor body is arranged between the electrodes; the resistor body is electrically connected with the electrode; a protective layer is arranged on an upper surface of the resistor body; a connectinggroove of a grid-shaped structure is dug in the substrate, the connecting groove is formed below the resistor body and is completely covered by the resistor body, an insulating protective fence is arranged between the electrodes, the insulating protective fence and the electrodes are matched to surround and reinforce the resistor body, the protective layer is composed of protective layer single bodies, the resistor body is composed of resistor body single bodies which are arranged in order, and each resistor body single body is formed by bonding a protective layer single body, a resistor andan insulating column in sequence from top to bottom. The chip resistor is favorable for researching the influence of different cutting lengths and cutting shapes on the resistor body in a laboratory,can be repeatedly used, and is favorable for saving experimental resources in the laboratory.

Description

technical field [0001] The invention belongs to the technical field of chip resistors, and in particular relates to a chip resistor. Background technique [0002] With the continuous development and maturity of radio frequency technology, chip thick film resistors, which are indispensable in radio frequency circuits, are widely used. The resistance adjustment methods of traditional chip thick film fixed resistors are divided into laser resistance adjustment method and sandblasting resistance adjustment method. Both laser trimming and sand blasting have an irreversible impact on chip resistance, which is not conducive to laboratory testing, and increases experimental waste and experimental funds. Currently, a special chip resistor for laboratory testing is required. Contents of the invention [0003] The object of the present invention is to provide a chip resistor to solve the problems raised in the background art above. [0004] In order to achieve the above object, th...
