The EnerChip™ CBC012 is a surface-mount, solid
state, thin film, rechargeable energy storage device
rated for 12µAh at 3.8V. It is ideal as a localized
on-board power source for SRAMs, real-time clocks
and microcontrollers which require standby power
to retain time or data. It is also suitable for RFID
tags, smart sensors, and remote applications which
require a miniature, low-cost, and rugged power
source. For many applications, the CBC012 is a
superior alternative to button cell batteries and
super-capacitors.
Because of their solid state design, EnerChip™
storage devices are able to withstand solder reflow
temperatures and can be processed in high-
volume manufacturing lines similar to conventional
semiconductor devices. There are no harmful gases,
liquids or special handling procedures, in contrast to
traditional rechargeable batteries.
The CBC012 is based on a patented, all solid state,
rechargeable energy cell with a nominal 3.8V output.
Recharge is fast and simple, with a direct connection
to a 4.1V voltage source and no current limiting
components. Recharge time is 10 minutes to 80%
capacity. Robust design offers thousands of charge/
discharge cycles. The CBC012 is packaged in a 5 mm
x 5 mm 6-pin DFN package. It is shipped in tubes,
tape-and-reel, or waffle pack trays.
