SNAPHAT® 锂钮扣电池，带晶体，STMicroelectronics这些电池和晶体选件设备是可折卸锂电源，封装在名为 SNAPHAT® 的特殊顶部。 SNAPHAT 扣入印刷电路板中表面安装 IC 的顶部。 还与 STMicroelectronics 的非易失 TIMEKEEPER® 封装兼容。### SRAM 和 NVRAM 附件
The 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
Do not wave solder SOIC to avoid damaging SNAPHAT® sockets.
