Battery Characteristics
Figure 4, page 7 illustrates the lithium coin cell dis-
charge 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).
UL Recognition
The M4Txx-BR12SH has been recognized by Un-
derwriters Laboratories under their Component
Recognition Program and carries U.L. File Num-
ber E89556.
Battery Life
For information on Data Retention Life and Battery
Storage Life, please refer to the Application Note
AN1012.
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 3, page 5 specifies,
only an average of less than 13 force-pounds is re-
quired 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
5). 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.
