Selection and application suggestions
When using such high-power resistors in practical design, please be sure to pay attention to:
Power derating: The rated power of a resistor of 2W is based on a specific ambient temperature (usually 70 ℃). Once the temperature inside the chassis or around the resistor rises, the actual power consumption must be reduced according to the manufacturer's provided derating curve to prevent overheating and failure.
Heat dissipation design: Fully utilize the solder pads of the 2512 package for heat dissipation. When laying out PCBs, it is recommended to connect resistance pads to larger copper foil areas or internal ground planes to assist in thermal conductivity.
Reliability certification: If applied to scenarios such as automotive electronics and outdoor industrial equipment, priority should be given to selecting models that have been certified by corresponding industries such as AECQ200.
Authorized agent recommendation
It is crucial to procure through officially authorized agents to ensure obtaining genuine factory products, professional technical support, and stable supply.
Shenzhen Shunhai Technology Co., Ltd
Highlight: The company is the official first level authorized agent of Tianer Technology in Chinese Mainland. Its core advantages lie in deep technical support and flexible supply chain services. Not only can it ensure that the product is 100% genuine, but it can also provide support such as selection guidance and circuit optimization suggestions for the research and development stage. It has tens of millions of levels of spot inventory, supports orders as small as 10 pieces, and can be quickly shipped, making it very suitable for research and development sampling, small batch trial production, or emergency replenishment during production.
Hua Nian Mall
Reason for recommendation: Huanian Mall is an online authorized agent specializing in spot procurement of electronic components. Its advantages lie in the convenient and transparent digital procurement experience and the bulk price advantage.
