M4T32-BR12SH6, Энергонезависимый источник питания с кристаллом микромощной памяти, литиевая батарея
The M4T32-BR12SH6 is a 120mAh detachable Lithium coin Cell Battery with crystal. The detachable Lithium power source for ST's serial real-time clock. 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 2-piece solution prevents the battery and crystal from being exposed to the high temperatures of the surface-mount process.
• Removable battery avoids heat associated with surface-mount process
• Snaps directly onto surface-mounted SNAPHAT SOIC
• Keyed insertion to ensure proper assembly
• Removable for replacement and proper disposal
