2、 Comparative analysis and selection considerations of market competitors
Comparing CRH2512J180RE04Z with similar products in the market is a necessary step in circuit design selection. Its main competitors come from international first-line and domestic major passive component manufacturers. When selecting, in addition to paying attention to basic parameters, key performance factors such as temperature coefficient, long-term stability, pulse load capacity, and whether derating is required should also be emphasized.
The following table summarizes several mainstream competitors with specifications similar to CRH2512J180RE04Z for your quick comparison and reference:
Brand/Model Packaging Resistance Accuracy Rated Power Temperature Coefficient Core Characteristics and Difference Analysis
Tian'er Technology CRH2512J180RE04Z 2512 180 Ω± 5% 2W ± 100 ppm/° C analysis object. Balancing power density and cost, thick film technology has high reliability and good resistance to sulfurization.
Guoju RC2512JK-7W56KL 2512 56K Ω± 5% 2W does not have a clear international universal brand, but has high recognition. But the example models have different resistance values and may require derating for use in high-power applications.
Fenghua High tech CUH2512F1R80E04Z 2512 1.8 Ω± 1% 2W ± 200 ppm/° C is a mainstream domestic brand with higher accuracy (± 1%). But the temperature coefficient is large, and the resistance drift is more obvious at high temperatures.
Samsung EGM25FU1R80DDS 2512 1.8 Ω± 1% 3.5W ± 50 ppm/° C with higher power (3.5W) and lower temperature drift. But the cost significantly increases, making it suitable for scenarios with extreme requirements for space and heat dissipation.
TE Connectivity CRGH2512J180R 2512 180 Ω± 5% 2W ± 200 ppm/° C, a product of the same level from an international manufacturer. Compared with Tian'er, the temperature coefficient (± 200ppm/° C) is twice as high, and the high-temperature stability may be slightly inferior.
Vishay (thin film resistor example) 2512 variable ± 0.1% typically<1W ± 25 ppm/° C ultra-high precision, ultra-low temperature drift. However, the power of thin film resistors in the 2512 package is generally lower (usually less than 1W), and heat dissipation is a weak link, so there is no direct competition.
Selection Summary:
The CRH2512J180RE04Z 2512 180R 5% 2W high-power resistor from Tian'er Technology has a clear positioning in the general high-power market. It achieves a good balance between 2W power, ± 100ppm/° C temperature drift, and cost through thick film technology, avoiding the shortcoming of insufficient power of thin film resistors and providing better high-temperature stability compared to some competitors. For applications that are not extremely precise but require stability and reliability, it is a comprehensive and cost-effective choice.
