TEC1-12706 Peltier thermoelectric cooler module

Description

TEC1-12706
Shipping is .50 in the USA no matter how many chips you buy - for example - if you buy 10pcs, your total is for the chips and .50 shipping = .50 total. I no longer offer the free shipping on these because too many people have been lying about non-receipt and we're sending all with tracking.
The 127-06 (127 interface, 6 amps) is a popular low cost Peltier chip. Ours are cleaner, smoother, higher quality than many others. Not all 12706's are the same; there are quite a few different ones, once you start buying them from different sources you will quickly see just how dramatic the difference can be.
Recommend running at 60-80 watts per module or below for excellent performance and longevity. Often, you should consider operating these at far lower voltages (for example 3-4 volts each). You'll be surprised at how much cool you get out of them at lower power draw, with far less heat being created. As a rule of thumb, Peltier efficiency (watts of heat pumped vs watts of electricity used) goes up exponentially with a decrease of voltage.
Wholesale inquiries welcome and consulting is always free. We use these modules for our own applications and can offer you advice and troubleshooting.

A note about Free Shipping for USA customers only: we ship from California. These are pricy modules and I want to offer the lowest total cost to you possible. To ship First Class Mail with a tracking number COSTS .65 plus packaging supplies. When you buy only 1 or 2 modules, we cannot absorb that cost, so
we
ship them using "Flats" rate which costs us a little over a buck. However, that means there IS NO TRACKING number, just like letters you get in the mail. It still gets to you just as fast and arrives in a pretty brown "CD mailer" pouch. If you must have tracking to sleep at night, either buy 3 or more modules, or opt for Priority Mail shipping at checkout. Hope that makes sense.

You can always run these at lower voltages for higher efficiency - as the current decreases, the coefficient of performance increases. At 12 volts the ΔT is almost 60°C. As you decrease the voltage and current draw, ΔT will decrease, but even at 1 volt there is a noticeable temperature difference, accompanied by the most efficient heat pumping you will find for this price.
Take your temperature control needs to a new level with solid-state.
