High-precision chip thick-film resistor

The invention discloses a high-precision chip thick-film resistor, and relates to the technical field of electronic components, a protection mechanism comprises a protection plate, the protection plate is connected with a first electrode and a second electrode through a clamping mechanism, a through groove is formed in the protection plate in a penetrating mode, the bottom of a groove cavity of the through groove is open, and the bottom of the through groove is open. A first clamping groove, a second clamping groove, a third clamping groove and a fourth clamping groove are formed in the top of the protection plate, the first clamping groove and the second clamping groove are symmetrical along the center point of the top of the protection layer, and the third clamping groove and the fourth clamping groove are symmetrical along the center point of the top of the protection layer. Tweezers are clamped in the first clamping groove and the second clamping groove or the third clamping groove and the fourth clamping
