2、 Core performance indicators
The rated power and heat dissipation are 2W (at a substrate temperature of 70 ℃), which is twice that of a conventional 2512 packaged 1W resistor, and can withstand higher currents and power consumption. Large size packaging provides sufficient heat dissipation area, combined with alumina ceramic substrate and thick film resistor layer, strong thermal stability under high temperature environment, reducing heat loss and damage risk.
Electrical accuracy and stability with a resistance value of 24 Ω, an accuracy of ± 5%, and a temperature coefficient of ± 100ppm/℃. The resistance drift is extremely small within a wide temperature range of -55 ℃ to+155 ℃, making it suitable for extreme environments such as outdoor, vehicle mounted, and industrial workshops. The maximum working voltage is 200V, and the instantaneous withstand voltage can reach 2000V pulses, suitable for low to medium voltage circuits.
The material and process adopt high-purity alumina ceramic substrate, ruthenium thick film resistor, and three-layer terminal electrode (silver/nickel/tin) design, which has excellent corrosion resistance and welding reliability. Lead free and halogen-free process, in line with global environmental standards, compatible with green production systems.
