Description: Chip model: TEC1-12704 Dimensions: 40x40x4.2mm component logarithm 127 Wire size: lead length 100±5mm RV standard wire single head 5mm tinned Internal resistance: 3.0~3.3Ω (ambient temperature 23±1°C, 1kHZ Ac test) Maximum temperature difference: ΔTmax (Qc = 0) 60 °C or more. Working current: Imax=12 (when rated voltage starts) Rated voltage: DC12V (Vmax: 15.5V) Cooling power: Qcmax 36W Assembly pressure: 85N/cm2 Working environment: Temperature range -55 °C ~ 83 °C (excessive ambient temperature will directly affect cooling efficiency) Packaging process: four weeks standard 704 silicone rubber seal Packing standard: foam box packaging, storage conditions, ambient temperature -10 °C ~ 40 °C Storage conditions: -40~60°C Note: There is a literal surface for the cooling surface, and no literal surface is the cooling surface. A heat sink or water-cooled must be installed on the heat sink surface, otherwise, it will burn out. (Please coating thermal silica gel regardless of water cooling or air cooling) Package included: 2 x TEC1-12704 40x40MM 12V3A Thermoelectric Cooler Peltier Refrigeration Plate
