TEP1-142T300 thermoelectric power generation sheet

The thermoelectric power generation chip (TEP1-142T300) is assembled with high-strength bismuth telluride thermoelectric material, high thermal conductivity, and high insulation DBC (direct bonded copper) ceramics and high-temperature solder, and is suitable for use in an environment where the hot end is 200 degrees. The semiconductor generator made of a semiconductor thermoelectric power generation sheet has the characteristics of no noise, long life, and stable performance. At the same time, it is small, lightweight, and easy to carry. It has become a widely used portable power supply.

Features:
1) High performance, with a temperature difference of 200 degrees, the power generation efficiency can reach 5%;
2) High reliability, common application life of more than 10 years;
3) High-temperature resistance, the hot surface can be used in an environment of 200 ℃;
4) High flatness (±0.02mm).
5) Lead length: about 15CM
6) Generator chip size: 40MM long * 40MM wide * 3.4MM thick

Application fields:
Fireplace fans, outdoor barbecue grills, power supplies for low-power electronic devices, heat waste, heat recycling, etc.

Regarding the distinction between hot and cold surfaces (electrode direction):
The lead wire of the temperature difference sheet is facing the body, the left black negative pole, the right red positive pole, the one facing up is used as the heat dissipation surface of the cold end, and the one facing down is used as the heating surface of the hot end.
Temperature difference 40 degrees: open circuit voltage 2.2V, generating current: 390MA;
Temperature difference 60 degrees: open circuit voltage 3.6V, generating current: 489MA;
Temperature difference 80 degrees: open circuit voltage 4.8V, generating current: 569MA;
Temperature difference 100 degrees: open circuit voltage 6.0V, generating current: 658MA;
Temperature difference 120 degrees: open circuit voltage 7.2, generating current: 759MA;
Temperature difference 140 degrees: open circuit voltage 8.4, generating current: 969MA;
The best matching resistance: is 3.3-4.3 resistance, and the use temperature is between -40 degrees to 200 degrees.
The above values are for reference only, and the current will be lost when wiring and booster boards are in actual use.
The operating temperature is between -40 degrees and 200 degrees.
