The TEC1‑12703 Peltier module is a 40×40 mm thermoelectric cooler that operates at 12 V and 3 A. It transfers up to ~30 W of heat, creating a temperature differential (ΔT) of around 65 °C, ideal for compact cooling or heating applications.
وحدة TEC1-12703 Peltier هي مبرد كهروحراري (thermoelectric cooler) بحجم 40×40 مم، يعمل بجهد 12 فولت وتيار 3 أمبير. تنقل حرارة تصل إلى حوالي 30 واط، مما يُحدث فرقًا في درجة الحرارة (ΔT) يبلغ حوالي 65 درجة مئوية، وهي مثالية لتطبيقات التبريد أو التسخين المدمجة.
The TEC1‑12703 is a compact, ceramic-based thermoelectric (Peltier) module sized at 40 × 40 × 3.5–4.7 mm. It contains 127 semiconductor couples and functions as a solid-state heat pump: one side becomes cold while the opposite heats up when DC is applied. With an optimal operating voltage of 12 V and max current of 3 A, it supports a peak power of approximately 27–30 W
