Product Summary

The M4T28-BR12SH1 is a detachable lithium power source for the non-volatile TIMEKEEPER surface mount SOIC (MH) package (28 and 44 pin). The M4T28-BR12SH1 contains both the battery and crystal and is designed to be snapped on after the SOIC is surface mounted on the PC board. Thus the two piece solution avoids the battery and crystal from having to be exposed to the high temperatures of the surface mount process.
