Coincel supercapacitors
Coin-cell supercapacitors are small devices that can store and quickly release electrical energy. They resemble batteries, but function differently. They have high capacity, charge quickly, and last a long time.
Supercapacitors have about ten percent of the energy density of rechargeable batteries of the same weight. Yet they can deliver significantly more power. They charge and discharge ten to a hundred times faster than a battery. They can also withstand many more charge cycles. This makes them suitable as replacements or supplements for batteries in applications with high peak loads.
Power density and energy density
Power density Indicates how quickly a component can absorb or release energy. This is important for applications that require short, powerful bursts of energy, such as starting a motor. Supercapacitors score highly in this regard because they can deliver energy quickly.
Energy density shows how much energy a component can store for an extended period. This is important for systems that require continuous power. Batteries usually have an advantage here, but supercapacitors complement this well.
SCHURTER's new coin cell supercapacitors
SCHURTER introduces a new series of coin-cell supercapacitors. They are available for horizontal mounting (SCCA) and vertical mounting (SCCC). The devices operate in systems up to 5.5 V and have a capacitance range of 100 to 1500 mF.
Applications
The new supercapacitors are used in a wide variety of devices and systems. Examples include uninterruptible power supplies, electronic equipment, renewable energy applications, and medical systems. They are often used as backups for real-time clocks. They are also suitable for memory backup, bridging battery changes, and for LED or audible alarms.
