description The utility model discloses a columnar patch precision metal film resistor, which relates to the technical field of electronic components and is characterized in that iron caps are embedded at the left and right ends of a ceramic matrix and a ceramic framework, a waterproof coating is arranged on the outer side of the middle of the ceramic matrix, and two ends of the waterproof coating are respectively adhered with two ends of the two groups of iron caps. The iron cap is a U-shaped structural member with two ends provided with convex steps, and each convex step comprises an upper side edge, a lower side edge and an arc-shaped protrusion. According to the utility model, the upper side edge, the lower side edge and the arc-shaped bulge of the iron cap are respectively connected with the outer encapsulating layer and the inner encapsulating layer to bear longitudinal stress, and the arc-shaped bulge is connected with the outer encapsulating layer, so that the contact area between the iron cap and the encapsulati
