Small Energy Devices

UMA series image
Murata has developed a miniature device with a high energy storage capacity, low ESR, fast charging and discharging and the ability to withstand load fluctuations. 
It may be used as a secondary battery in the same way as a capacitor. 
This energy device achieves better charge/discharge characteristics and has an extended service life superior to conventional batteries. 

Well suited as a power supply for wearable devices or sensor nodes for wireless sensor networks, this device maintains flat voltage characteristics while accommodating a wide range of load characteristics.
