SNAPHAT M4T28-BR12SH1 48 mAh Lithium Coin Cell Battery With Crystal – 5 PACK FREE SHIPPING The M4Txx-BR12SH SNAPHAT®top 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. All features: Provides battery backup power for serial real-time clock, non-volatile TIMEKEEPER® and supervisor devices in the 28- or 44-pin SNAPHAT®SOIC packageRemovable battery avoids heat associated with surface-mount processSnaps directly onto surface-mounted SNAPHAT SOIC
