Double-layer Semiconductor Refrigeration Sheet TEC2-19003 Power 12V3A 30*30mm Large Temperature Difference 80 Degrees | Электроника

Chip type: TEC2-19003

Outline size: 30*30*6.7mm components, logarithm 190 pairs.

Conductor specification: lead length 150± 8mm RV standard conductor single head 5mm tin plating.

Internal resistance: 3.8-4Ω (ambient temperature 23± 1 C, 1kHZ Ac test)

Maximum temperature difference: above 85 C

Working current: Imax=3A

Rated voltage: DC12V (maximum voltage: 15.5V)

The cooling power is 35W (the cooling surface temperature is too high, which reduces the cooling power).

Assembly pressure: 85N/cm2

Working environment: temperature range -55 ~ 83 C (high ambient temperature will directly affect refrigeration efficiency).

Packaging process: Standard 704 silicone rubber seal

Packing standards: foam box packaging, storage conditions, ambient temperature -10 ~ 40 C

Storage conditions: -40~60 C

Power requirements: single voltage 12V, current 3A or more power supply (serial and parallel).

Device characteristics: red line cathode, black line negative electrode (with literal cold surface, no literal heat dissipation surface).
