Mechanical information

2.1

Note:

Battery characteristics

Figure 3 on page 8 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.

These batteries contain no mercury (Hg), cadmium (Cd), or lead (Pb).

2.2

UL recognition

The M4Zxx-BR00SH has been recognized by Underwriters Laboratories under their

Component Recognition Program and carries U.L. File Number E89556.

2.3

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 2 on page 6 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 is 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 SNAPHAT top should be grabbed by the narrow end to avoid bending the

pins.

To avoid draining battery do NOT place SNAPHAT pins into conductive foam.

To avoid damaging SNAPHAT sockets do NOT wave solder SOIC.
