General Description

The DS3802 battery cap is a snap-on lithium power source for Dallas Semiconductor’s 40mm BGA NV SRAM modules including the DS3832C-311 and DS3816C-511.

After a host BGA module has been soldered in place and cleaned, the DS3802 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 designed to maintain mechanical and electrical contact with its host module even during severe shock and vibration.

Key Features

  • Houses 380mAh primary lithium batteries Snaps directly onto a surface-mounted 40mm ball-grid array (BGA) nonvolatile (NV) 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 Two attachment flanges latch onto host BGA module to provide a strong, semipermanent attachment Industrial.
