Supercapacitor boasts large capacity, low ESR

Murata has launched what it calls the world's lowest-profile 0.4-mm supercapacitor. The DMH Series of supercapacitors is designed to facilitate peak power assist with lithium-ion batteries in wearable and other portable devices such as smartphones and smartcards.

A supercapacitor is a storage device with over 100 times the capacity of ceramic and electrolytic capacitors. So it provides a longer work life than common secondary batteries. Murata's new supercapacitor boasts a capacity of 35 mF and low equivalent series resistance (ESR) that allows it to enable peak power assist in tens of milliseconds.

Furthermore, the DMH Series supercapacitors' compact size and low-profile design ensure increased output and power stability in portable electronic devices like wearables. Murata started the production of these supercapacitors in February 2017.
