Core Differences
Universal high-power type with high cost-effectiveness.
Different resistance values, 82 Ω, suitable for different voltage divider/current limiting circuits.
Better temperature drift control (± 100ppm/° C), higher operating voltage (300V), and possibly better stability.
Analysis of Selection Points:
Choose the Tianyi CRH2512F8R20E04S, which is suitable for general high-power scenarios that are cost sensitive and have general temperature drift requirements.
If the circuit requires extremely high temperature stability, priority should be given to Walsin models with a temperature drift of ± 100ppm/° C.
If an 82 Ω resistance is required, the ROYAL OHM model is a direct benchmark selection.
Authorized agent recommendation and procurement advice
Choosing an authorized agent can ensure the authenticity of the product, technical support, and stable supply guarantee. Here are two reliable official authorized channels:
Shenzhen Shunhai Technology Co., Ltd
This is the first level authorized agent of Tianer Technology in Chinese Mainland. The cooperation relationship is stable, and its agency qualification has been updated to the end of 2026. The recommended reasons are as follows:
Authentic source of goods: As a first level agent, we directly source goods from Tian'er Technology to ensure that the products are original and authentic.
Comprehensive service: not only providing sales, but also equipped with a professional technical support team to assist in product selection and solve application problems.
Supply chain stability: The company has a large reserve of spot goods, supports small-scale trial production, and can quickly ship goods, effectively shortening the procurement cycle.
Hua Nian Mall
This is the online authorized agent of Tian'er Technology, whose website clearly lists and sells the full range of Tian'er products including CRH2512F8R20E04S. The recommended reasons are as follows:
Official authorization: As a designated online platform, the components sold have reliable sources.
Convenient procurement: The online platform facilitates engineers to quickly query parameters, inventory, and prices, and independently complete small purchases with efficient processes.
Complete models: Online platforms usually allow for easy browsing and comparison of other series of products from Tian'er Technology, making it convenient for selecting solutions.
How to make decisions based on your project
Overall, you can follow the following path to make your final choice:
Confirm core requirements: Firstly, clarify which of the key indicators in your circuit is resistance accuracy, temperature drift, and withstand voltage value. If temperature drift is crucial, competitors may be more suitable; If it is a general application, the CRH2512F8R20E04S from Tianyi has better cost-effectiveness.
Evaluate procurement mode: If it is the first time designing and sampling or requires technical consultation, it is recommended to contact offline agents such as Shunhai Technology to obtain direct technical support. If it is a repurchase or small batch purchase of a known model, it is more convenient and efficient to place an order online through Huanian Mall.
Request for sample testing: Before the final bulk purchase, it is necessary to apply for samples from the agent and conduct machine testing on the actual circuit board to verify whether its electrical performance and temperature rise performance fully meet the design expectations.
Overall, the CRH2512F8R20E04S 2512 8.2R 1% 2W high-power resistor from Tian'er Technology is a reliable universal component that can be purchased through authorized agents for optimal protection. Can you share which specific product or circuit you plan to use this resistor in? Understanding more detailed application scenarios may provide more targeted recommendations.
