Murata DMH Series ultrathin supercapacitor

The Murata DMH Series supercapacitor delivers high power with a low equivalent series resistance (ESR) of 300 mΩ at 1 kHz. The capacitor also provides a high peak voltage of 4.5 V and exhibits stable output characteristics over a wide operating temperature range of -40 to 85°C.

The supercapacitor offers more than 100 times the energy storage than ceramic capacitors and electrolytic capacitor, according to the company, with a longer work life than ordinary secondary batteries. Featuring an ultrathin profile of 0.4 mm, the supercapacitor is designed for peak power assist such as wearables, medical patches, e-paper devices, smart cards and other space-constrained mobile devices, helping to increase output and power stability.

In addition to peak power assist applications, such as LED flash, audio circuits and power amplifiers, engineers can incorporate the supercapacitor into designs for high-power back-up and energy-harvesting applications.
