Ultra-thin supercapacitor designed for peak power assist in wearables and smart devices

Mouser now stocks the DMH Series supercapacitor from Murata. The device features an ultra-thin profile of just 0.4mm; the DMH series supercapacitor is designed for peak power assist in wearables, smart cards, medical patches, e-paper devices, and other space-constrained mobile devices. The supercapacitor delivers high power with a low ESR of 300milliohms at 1kHz. The capacitor also provides a high peak voltage of 4.5V and displays stable output characteristics over a wide operating temperature range of minus 40C to 85C. The device offers more than 100 times the energy storage than ceramic capacitors and electrolytic capacitors with an extended work-life compared with ordinary secondary batteries. The device is ideal for peak power assist in small electronics. It helps 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 backup and energy-harvesting applications.
