M4Txx-BR12SH SNAPHAT
The STMicroelectronics M4T28-BR12SH1 is a battery and crystal within a detachable SNAPHAT package. The SNAPHAT package snaps onto the PCB, directly on top of an SMD SOIC package. This lithium power source is removable which avoids potential issues caused by the heat in surface mounting processes. The M4T28-BR12SH1 works with the ST range of serial real-time clock and non-volatile TIMEKEEPER® SOIC packages, in 28 or 44 pin variants.
The M4T28-BR12SH1 contains a BR1225 48mAh, 3V battery which can be used in temperatures from 0°C to +70°C.
Features and Benefits
- M4T28-BR12SH = 48 mAh
- M4T32-BR12SH = 120 mAh
SNAPHAT® Lithium Coin Cell Battery with Crystal, STMicroelectronics
These Battery and Crystal Option devices are detachable lithium power sources housed in special top called SNAPHAT®. The SNAPHAT is snapped on the top of the surface-mounted IC in the Printed Circuit board. Also compatible with the non-volatile TIMEKEEPER® package by STMicroelectronics.
