Supercapacitors have over 100 times the capacity of ceramic capacitors and electrolytic capacitors, and it is a storage device with a longer work life than ordinary secondary batteries.

Murata’s recently launched DMH series supercapacitors feature a low profile design of 0.4mm while having low ESR for use in thinnest devices. By using the 4.5V capacitor for peak power assist with lithium ion batteries in small electronics, the product contributes to increased output and power stability as well as functional improvement of the device.

The 0.4mm DMH capacitors target limited space applications such as various wearables, mobile electronics, smart cards, electronic paper devices and similar applications.
