DMH Series Supercapacitor

By Murata Electronics 205

DMH Series Supercapacitor

Murata's DMH series of supercapacitors have an extremely small construction while having world-leading low ESR. Using the capacitor for peak power assist in small electronics, the product contributes to increased output and power stability as well as functional improvement of the device. By optimizing construction materials and structure, the first product in the DMH series has been designed to have 35 mF, 4.5 V, and 300 mOhms in just a 20 mm x 20 mm x 0.4 mm package.

The DMH series accommodates use in limited space and it is ideal for use in various wearable devices, mobile electronics, smart cards, electronic paper devices, and similar applications.

Features
  • Assist peak power for coin cell batteries and enhance the function of devices
  • Can be mounted in dead space (e.g. under a battery) and save board space
  • Extend active time until system shutdown
  • High capacitance for energy buffer
  • 4.5 V is ideal for peak power assist with lithium-ion batteries
Applications
  • Smart watches, fitness bands, and tracking devices
