Frequently Asked Questions

What is the maximum temperature difference I can apply to the SP1848-27145 TEG?

The SP1848-27145 module is rated for a maximum operating temperature of 150°C on its hot side. The temperature differential (ΔT) between the hot and cold sides directly determines the output voltage and current. For optimal performance and longevity, do not exceed the 150°C limit on the heated face, and ensure the cold side is adequately heatsunk.

What output voltage and current can I expect from this thermoelectric generator?

Output is proportional to the temperature gradient. At a 100°C differential, the module produces approximately 4.8V open-circuit voltage and can deliver up to 669 mA. Performance scales linearly at lower differentials (e.g., ~0.97V at 20°C ΔT). For stable power delivery, pair the TEG with a voltage booster or maximum power point tracking (MPPT) circuit.

How do I properly install and interface the SP1848-27145 module?

Apply a thin layer of thermal grease to both ceramic faces. Mount the 'model number' side (typically the cold side) to a heatsink or cooling mass. Apply heat to the opposite face. Electrically, the two solder pads provide DC output; polarity is indicated on the module. For microcontroller integration, use the raw output with a DC-DC booster or connect to a power management IC for battery charging.

Can this TEG module be used for cooling (as a Peltier cooler)?

While based on Peltier technology, the SP1848-27145 is specifically optimized and formulated for power generation (Seebeck effect). Its internal construction is tuned for efficient energy conversion from heat, not for active cooling. Applying a voltage for cooling purposes is not recommended and may result in suboptimal performance or damage.
