CRH2512J470KE04Z is a high-power thick film surface mount resistor widely used in fields such as power management, industrial control, and consumer electronics. This model adopts the 2512 package specification, with external dimensions of 6.35mm × 3.10mm. Compared with conventional surface mount resistors, it has a larger heat dissipation area and can carry higher power loads.
From the naming convention of the model, each character of CRH2512J470KE04Z represents a specific parameter. CRH represents the high-power thick film resistor series, 2512 represents the package size, J represents the accuracy level of ± 5%, 470K represents the resistance value of 470k Ω, and E04Z is the packaging code. The rated power of this resistor reaches 2W, with a working temperature range covering -55 ℃ to+155 ℃ and a temperature coefficient of ± 100ppm/℃. It is suitable for circuit designs that require high power and stability.
In terms of electrical performance, the resistance range of CRH2512J470KE04Z is 465.3k Ω to 474.7k Ω (calculated with ± 5% accuracy), with a working voltage of 250V and an overload voltage of up to 500V. It uses an alumina substrate with a RuO2/Ag resistor layer structure, and achieves good insulation protection and mechanical strength through glass primary packaging and epoxy resin outer packaging.
The 2512 package resistor has a natural advantage in heat dissipation performance due to its larger volume. Compared with small-sized packages such as 1206 and 0805, the 2512 package can carry greater power and is suitable for circuit designs that require high currents. In practical applications, engineers can choose 1W, 2W or higher power versions according to power requirements, while considering heat dissipation measures during PCB design, such as using large-area copper foil or increasing heat dissipation channels.
