TDK CeraCharge rechargeable solid-state battery now available from RS

RS Components (RS) has announced that it is now stocking CeraCharge, the first rechargeable solid-state SMD battery from TDK.

Small, easy to assemble, and intrinsically safe, CeraCharge, according to TDK, combines the capacity of Lithium-ion (Li-ion) batteries with the safety and affordability of ceramic multilayer technology. It is described as a great fit for a variety of IoT devices, from smart meters through to programmable logic controllers (PLCs), Bluetooth beacons (BLE), real-time clocks (RTE), and wearables.

Unlike most battery technologies, CeraCharge is based on a multilayer technology that resembles the structure of Multilayer Ceramic Chip Capacitors (MLCCs). Its solid ceramic electrolyte eliminates the risk of fire, explosion or leakage that comes with conventional liquid electrolytes.One of the smallest devices in its category, CeraCharge comes in a compact EIA 1812 case size that can be easily integrated into a variety of IoT devices. Highly flexible, it can undergo reflow soldering and be connected in series or in parallel, adapting to multiple design requirements. It can withstand operating temperatures between -20° to +80° C meaning it can be deployed safely, across a wide range of applications.

CeraCharge is designed to be durable and long lasting, offering reliable power supply over more than 1,000 recharging cycles. Its 100 µAh nominal capacity is approximately 1,000 times that of a conventional capacitor, but in the same case size.

Other product specifications include a small overall footprint (4.4 x 3.0 x 1.1 mm), nominal voltage of 1.5V, operating voltage of up to 1.6 Vop, and nominal discharge current of 20 µA.
