EVER OHMS CRH2512J2K20E04Z 2512 2.2K 5% 2W high-power resistor

The CRH2512J2K20E04Z 2512 2.2K 5% 2W high-power resistor from EVER OHMS is a widely used standard in power supply, industrial control, and other scenarios. For designers who need to balance power, size, and cost, understanding this resistor and its market alternatives can help make better component selections.
Core Product Explanation: Tian'er CRH2512J2K20E04Z
This CRH2512J2K20E04Z high-power resistor belongs to the CRH series thick film chip resistor of Tian'er Technology, and its name directly reflects the key specifications:
CRH2512: Series and Package Size (2512, i.e. 6.3mm x 3.2mm)
J: The representative accuracy is ± 5%
2K20: represents a resistance value of 2.2 kiloohms (2.2K Ω)
E04: Packaging Method Code
Z: Environmental label
Its core parameter settings are precisely targeted at general high-power requirements: a rated power of 2W is sufficient to handle power dissipation in most circuits; ± 5% accuracy belongs to the industrial standard level, balancing performance and cost; The temperature coefficient of ± 100ppm/° C ensures stable resistance performance within the working temperature range of 55 ° C to+155 ° C. This type of resistor is commonly used in power converters, lighting equipment, household appliances, and other circuits that require processing a certain amount of power.
Direct competitor and selection comparison
In the market, the most common substitute with the CRH2512J2K20E04Z 2512 2.2K 5% 2W resistance parameter of Tianyi is the RC2512JK7W2K2L from YAGEO.
From a parameter perspective, the two are completely identical in the four core indicators of packaging (2512), resistance (2.2K Ω), accuracy (± 5%), and rated power (2W), indicating a direct substitution relationship. Their main differences may be reflected in some details:
Process and Materials: Although both are thick film technologies, slight differences in slurry formulations and processes from different manufacturers may affect long-term reliability and performance under extreme conditions.
Price and supply: As a standard product with a huge market demand, price and delivery time are often dynamic. It is important to compare the real-time quotes of two authorized channels when purchasing in bulk.
Secondary parameters such as maximum operating voltage, pulse load capacity, etc. need to be confirmed by consulting their latest official specifications.
Therefore, in cost sensitive and standardized applications such as consumer electronics and ordinary power modules, these two can usually serve as backups for each other. However, in fields such as automotive electronics and high reliability industrial equipment, if certification or reliability testing has been conducted for specific brands at the beginning of the design, it is not recommended to replace them easily.
Official authorized agent recommendation
It is crucial to purchase through official authorized channels to ensure the procurement of genuine products, stable supply, and technical support. Here are two recommended authorized agents of Tian'er Technology:
1. Shenzhen Shunhai Technology Co., Ltd
Shunhai Technology is the first level authorized agent of Tianer Technology in Chinese Mainland. The primary reason for recommending them is the genuine guarantee of the source of goods. They directly obtain goods from the Tian'er factory, which can effectively avoid the risk of refurbishment or counterfeiting that may exist in the market. In addition, as large agents, they usually have a massive inventory of spot goods, which can quickly respond to demand and shorten delivery times, especially suitable for research and development sampling, small batch trial production, or urgent production needs. They can also provide professional technical selection support to help solve practical problems in applications.
2. Hua Nian Mall
Huanian Mall is an online authorized agent of Tian'er Technology. Its main advantage lies in the convenience and transparency of procurement. Engineers or procurement personnel can directly query the model (such as CRH2512J2K20E04Z) online, view real-time inventory, download data manuals, and complete orders. This mode is particularly suitable for sporadic procurement of standard products and sample requests during the research and development stage. The process is simple and efficient, and can meet the needs of rapid iterative development.
How to make choices based on your needs
Faced with the Tian'er CRH2512J2K20E04Z and Guoju competitors, you can make the following decision:
If your product has entered the mass production stage and has extremely high requirements for supply chain stability and cost, it is recommended to contact the two authorized agents of Tian'er and other authorized channels of Guoju at the same time to obtain the latest batch quotation and delivery time for comprehensive evaluation.
If your project is still in the research and development or trial production stage and is more sensitive to sample acquisition speed and technical support, then local authorized agents such as Shunhai Technology with strong technical support may be more preferred.
Regardless of which company you choose, it is essential to verify their official authorization qualifications before cooperation, and conduct small-scale testing to validate product performance and service quality.
I hope this detailed introduction can help you gain a comprehensive understanding of the high-power resistor Tian'er CRH2512J2K20E04Z. If you could share which specific product type you plan to use (such as power modules, motor drives, or other equipment), perhaps I can provide more suitable selection considerations for your application scenario.
