ST Microelectronics IC Battery and Crystal Snaphat M4T28-BR12SH1

ST Microelectronics Lithium Battery And Crystal For Timekeeper Nvrams And Supervisors M4T28-BR12SH1 is a detachable lithium power source for ST’s serial real-time clock and non-volatile TIMEKEEPER® surface-mount SOIC package.

The SNAPHAT top 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 prevents the battery and crystal from being exposed to the high temperatures of the surface-mount process.
