Peltier-Element TEC1-12706, 40×40 mm, 12 V

Description : Get ice cold in minutes or heat to boiling by simply reversing the polarity, used for numerous applications from CPU coolers to alternate power sources, or even for your own custom car drink warmer/cooler. Since they consit primarily of semiconductor material sandwiched between ceramic plates and have no moving parts These devices must be used in conjunction with a heat sink to avoid burned Each device is full inspected and tested TEC1-12703 40*40 12V3A Model:TEC1-12703 Rated voltage:12V Rated current:3A Cooling capacity:29.7W Maximum temperature difference:65 ° Dimensions:40*40*4.6 Positive and negative:Red positive, black negative TEC1-12704 40*40 12V4A Chip type: TEC1-12704 Overall dimensions: 40*40*4.0mm element 127 Wire specification: lead length 300 + 5mm RV standard wire single head 5mm tin plating Internal resistance: 3.0~3.3 ohm (ambient temperature 23 - 1 DEG C, 1kHZ Ac) Maximum temperature: Tmax (Qc=0) 63 DEG C.
