EnerCera Coin

Issues to be solved

Have you ever faced issues such as

  • A compact power storage solution that maintains its charge state for long periods of time and can be used in the punishing conditions experienced by vehicle-mounted devices, factory equipment, and outdoor applications, and offers unimpaired capacity and output higher than 85℃ / 185℉.

  • Inability of batteries to withstand reflow soldering limits the cost reductions that are possible in manufacturing processes, because of the need to attach these batteries using a separate process.

  • Rechargeable Lithium-ion batteries must be coupled to a Power Management IC and this causes obstacles to design simplification, cost reduction, and PCB miniaturization.

EnerCera Coin to the rescue!

EnerCera Coin features

  • A thin (as thin as 1mm) and compact rechargeable coin cell that can provide the power required by wireless communications applications with minimum voltage drop and withstand temperatures of up to 105℃ / 221℉

  • Reflow solderable to circuit boards for high mass-producibility

  • Does not require a charger IC and can be rapidly recharged at constant voltage/constant current
