Applications Tips
Cautions
1. Do not heat TE module more than 200oC (TEC assembled
3. Connect TE sub-mount to a DC power supply in
at 230oC) or 160oC (TEC assembled at 183oC).

2. Do not use TE module without attached heat sink at hot
4. Do not apply DC current higher than Imax.

Installation
Object to be cooled
1. Soldering of object to be cooled.
Method suitable for a TE module with the metallized cold side
(Ordering Options. Item F). Soldering requires careful procedures:
A. Never overheat TEC (Cautions. Item 1).
B. Use solder with melting point less than TEC mounting solder
(Ordering Options. Item C).
Mounting
2. Gluing of object to be cooled.
Method available by glues with good thermoconductive properties.
Not recommended for high vacuum aplications and long operations
