Problems solved by technology

Since the heat dissipation capacity of ceramics is far inferior to that of metals, there is still a certain limit to the power used, and the thickness of the resistance element prepared by printing is also limited, so it is still difficult to realize a lower resistance resistor.
In addition, for resistor manufacturing enterprises, the overall process of this method is long, the process is complicated, and the mass production is relatively poor.

Embodiment 1

[0039] This embodiment is an embodiment of a resistor.

[0040] see figure 1 As shown, this embodiment provides a resistor 10 including a resistor unit 12 having an upper surface 13 and a lower surface 14 . The resistance unit 12 may be an alloy material with a low temperature coefficient of resistance such as manganese-copper-tin, nickel-chromium-aluminum-silicon or iron-chromium-aluminum. The lower surface of the resistance unit 12 has a trimming region 15 , and the preset resistance value of the resistance unit 12 is obtained by trimming the resistance unit 15 . The upper surface 13 may be coated with an anti-oxidation material film (not shown) to ensure that the resistor 10 is protected from oxidation during manufacture, storage and processing. The anti-oxidation film material can be rosin, active resin, azole and so on. The anti-oxidation film material is located on the upper surface of the resistance unit. The anti-oxidation film material can be applied by spraying, ...
