The DS3800 Battery Cap is a snap–on lithium power source for Dallas Semiconductors 40mm ball–grid array (BGA) Nonvolatile SRAM modules. After a host BGA module has been soldered in place and cleaned, the DS3800 Battery Cap is snapped onto the module to serve as the secondary power supply. The Battery Cap is keyed to prevent incorrect attachment and is design.
Houses 400 mAh primary lithium battery Snaps directly onto a surface
–mounted 40mm ball
–grid array (BGA) Nonvolatile SRAM module Attaches after host BGA module has been surface
–mounted to protect lithium battery from the high temperatures of reflow soldering Maintains mechanical and electrical connection with BGA module even during severe shock and vibration stresses Four attachment flanges latch onto host BGA module to provide strong, semi
–permanent attachment. Flanges can be broken off for cap removal Industrial temperature range of
–40°C to +85°C
