Key parameter description
Power derating design: In practical use, it is recommended to design at 50%~70% of the rated power (such as using a 2W resistor with 1-1.4W) to avoid high temperature failure.
Temperature drift effect: In high temperature environments, the resistance deviation of thick film resistors (± 200 ppm/℃) may be four times higher than that of metal films/alloys (± 50 ppm/℃).
Package compatibility: The 2512 size (6.4mm × 3.2mm) needs to match the IPC7351 standard pad design to avoid virtual soldering.
If you need to further verify the model or obtain samples, you can contact the brand agent (such as Shunhai Technology, Huanian Mall) to inquire about the specific inventory and specifications of the 1.1 Ω resistance value. In actual selection, it is necessary to make a comprehensive decision based on the batch unit price (reference: alloy resistors are about ¥ 1.5~2.5/piece, thick film resistors are about ¥ 0.3~0.6/piece) and supply cycle.
