Guoju RC2512 series: As a direct benchmark product, Guoju's 820 Ω resistor temperature coefficient is usually ± 200ppm/℃, and its resistance stability in high temperature environments is slightly inferior to CRH2512J820RE04Z 2512 820R 5% 2W high-power resistors. However, the price advantage is obvious, with a bulk purchase unit price of about 0.35 yuan, suitable for cost sensitive and mild working conditions in consumer electronics scenes.

Fenghua High tech FH2512 series: The power level is the same, but in long-term stability testing, the resistance drift rate of CRH2512J820RE04Z 2512 820R 5% 2W high-power resistor is lower, and the parameter change is controlled within 0.5% after 1000 hours of full load operation. Fenghua products are more suitable for standard industrial applications in domestic substitution projects.

Weishi CRCWHP series: The temperature coefficient can reach ± 50ppm/℃, with better accuracy performance, but the unit price is about 0.75 yuan, which is 30% higher than Tian'er products, and the delivery time is as long as 68 weeks. Weishi products are suitable for high-end scenarios such as communication equipment and medical instruments that require extremely high temperature stability.
