RS Components now stocks CeraCharge, the industry’s first rechargeable solid-state SMD battery from TDK. Small, simple to assemble, and intrinsically safe, the device incorporates the capacity of Li-ion batteries with the safety and affordability of ceramic multilayer technology. The device is an excellent fit for a mixture of IoT devices, from smart meters through to PLCs, Bluetooth beacon, RTE and wearables.
Unlike many battery technologies, the solution is based on a multilayer technology that resembles the structure of MLCCs. Its solid ceramic electrolyte removes the risk of fire, explosion or leakage that arrives with conventional liquid electrolytes.
One of the smallest in its category, the device is supplied in a compact EIA 1812 case size that combines easily into an assortment of IoT devices. A highly flexible solution, it can undergo reflow soldering and be linked in series or in parallel, adjusting easily to numerous design needs. It can withstand operating temperatures between -20C to +80C meaning it can be deployed safely, over a broad variety of applications.
The device is durable and long-lasting, providing reliable power supply over more than 1,000 recharging cycles. Its 100µAh nominal capacity is around 1,000 times that of a conventional capacitor but in the same case size.
The device offers a small overall footprint (4.4mm x 3mm x 1.1mm), nominal voltage of 1.5V, operating voltage of up to 1.6Vop, and nominal discharge current of 20µA.
