9 / 16 page M4T28-BR12SH, M4T32-BR12SH Mechanical information 9/16 4.1 Battery characteristics Figure 3 on page 10 illustrates the lithium coin cell discharge rate for a given load. This demonstrates the characteristically flat voltage level supplied by the battery until very near the end of its life. These discharge levels have been greatly accelerated in comparison to the normal, actual usage. Note: These batteries contain no mercury (Hg), cadmium (Cd), or lead (Pb). 4.2 UL recognition The M4Txx-BR12SH has been recognized by Underwriters Laboratories under their Component Recognition Program and carries U.L. File Number E89556. 4.3 Battery life For information on data retention life and battery storage life, please refer to the application note AN1012. 4.4 General notes ST has conducted experiments using a manual press which determined that if approximately 60 pounds of force is applied to the top of the SNAPHAT®, battery damage and/or die cracks could be induced. As Figure 2 on page 8 specifies, only an average of less than 13 force-pounds is required for proper insertion. We recommend that no more than 40 pounds of force be applied during SNAPHAT insertion. If a manual press in employed, it is very important that it be calibrated such that it cannot exceed this limit. To remove the SNAPHAT top for replacement, a DIP/IC extractor tool should be used (see Figure 4). The SNAPHAP top should be grabbed by the narrow end to avoid bending the pins. Caution: To avoid draining battery do NOT place SNAPHAT pins into conductive foam. Caution: To avoid damaging SNAPHAT sockets do NOT wave solder SOIC. |
