墨西哥采购需求：高压电阻器、功率电阻器、制动电阻器、变阻器、负载箱、动态制动电阻器

I'm currently in the market for a ceramic non-inductive wire wound resistor with a resistance of 40 ohms and a power rating of 20 watts. I require components with a tolerance of 5%. My projected annual usage for these resistors is approximately 12,000 units, so I'm looking for reliable suppliers who can meet this demand consistently. In addition, I'm interested in alternatives to the Ohmite brand for this specific product. If you have suitable options or can provide samples, I'd appreciate details on pricing, lead times, and any technical specifications relevant to your offerings. Looking forward to your prompt response.
