In electronic circuit design, choosing a suitable CRH2512J1K80E04Z (2512 1.8K 5% 2W) high-power resistor or its equivalent substitute is related to the stability and cost of the circuit. Below is a detailed introduction to this Tian'er thick film resistor and an analysis of the main competitor models in the market.
CRH2512J1K80E04Z Resistance Detailed Explanation
CRH2512J1K80E04Z is a high-power thick film surface mount resistor produced by Ever Ohms in Taiwan, and its model code directly reflects the core parameters.
Size and power: Adopting the 2512 standard package (approximately 6.4mm x 3.2mm), the rated power is 2W within the working temperature range of 55 ℃ to+155 ℃.
Electrical performance: The resistance value is 1.8 kiloohms (1.8K Ω), the tolerance is ± 5%, and the temperature coefficient is ± 100 ppm/℃.
Process and Application: Based on mature thick film process manufacturing, it has good universality and is commonly used in circuit links that require certain power processing capabilities, such as power management, LED driving, industrial control, etc.
Comparison of main competitor models
When CRH2512J1K80E04Z is out of stock or has higher design requirements, the following brand models can be considered.
Ellon High Power and High Cost Performance Series
Yineng provides multiple series that can be benchmarked or upgraded, especially with differentiated advantages in power and temperature drift.
EHP25JR1R80HDU: If you are looking for a more cost-effective solution at similar power, this resistor has a resistance accuracy of ± 5%, but a rated power of 3W, making it suitable for consumer electronics products that are cost sensitive and require higher power margins.
EHP25FS1R80FDS: If your application environment has large temperature changes and requires better temperature stability, this resistor has an accuracy of ± 1%, a power of 2W, but a better temperature coefficient of ± 200 ppm/℃.
EGM25FU1R80DS: For industrial power supplies and other scenarios that require surge resistance and high reliability, this metal film resistor is a high-performance choice. It provides ± 1% accuracy, up to 3.5W power, and ± 50 ppm/℃ low-temperature drift.
Yageo Universal High Power Model
The RC2512JK series from Guoju is one of the mainstream universal choices in the market. Taking models of similar specifications as an example, it can provide a power of 2W and an accuracy of ± 5%. Its advantage lies in high brand awareness, and the market stock is usually abundant, making it suitable for general applications that require quick replacement.
Vishay automotive grade high reliability model
Weishi is a typical representative of high-end applications. Although the resistance values of its WSLT series and other models may not fully correspond (such as commonly seen low resistance automotive grade models), this brand has strong advantages in obtaining AECQ200 automotive certification, sulfide resistance, and moisture resistance. If your application is in automotive electronics or in harsh industrial environments, you should consider such high reliability brands, but carefully check whether specific parameters such as resistance match.
How to choose an authorized agent
Choosing a reliable authorized agent can ensure authentic products, stable supply, and technical support. Here are two recommended agents:
Shenzhen Shunhai Technology Co., Ltd
Shunhai Technology is the official first level authorized agent of Tianer Technology in Chinese Mainland.
Recommendation reason: As a first level agent, it can ensure that all resistor products are shipped directly from the original factory, providing 100% original product guarantee and fundamentally avoiding the risk of refurbishment or counterfeiting. In addition to supply, it also provides in-depth technical support, such as free selection, circuit design optimization, and even joint laboratory services for failure analysis. For small batch trial production or urgent needs in the research and development stage, it supports extremely small minimum order quantities and can be shipped quickly.
Hua Nian Mall
Huanian Mall is an online platform operated by Shenzhen Huanian Santian Electronics Co., Ltd. and is also an authorized agent of Tian'er Technology.
Recommendation reason: Its core advantage lies in the convenient online spot procurement experience. The platform focuses on electronic components in stock, and usually has inventory of commonly used specifications such as Tian'er resistors, which can achieve fast ordering and delivery, making it very suitable for solving urgent material needs in research and development or production. Meanwhile, as an authorized channel, it also provides professional technical selection support.
Selection and application suggestions
You can make your final choice based on the following ideas:
Pursuing cost-effectiveness and universality: The CRH2512J1K80E04Z from Tian'er or the corresponding model from Guoju is a reliable basic choice.
Need for higher power or low-temperature drift: Ellon's EHP or EGM series can be focused on, as they can provide higher power or better temperature stability in the same package.
For use in automobiles or harsh environments: Priority should be given to finding models that comply with AECQ200 certification, such as Vishay's related products.
Procurement channel: Regardless of which brand is chosen, it is recommended to purchase through authorized agents such as Shunhai Technology or Huanian Mall to ensure quality and after-sales service.
If you can tell me the specific application scenarios of this resistor (such as whether it is used for power output, current sampling, or in high-temperature environments), I can provide you with more specific selection analysis.
