January 2012:- Murata Electronics North America developing the thin, low-resistance, electrical double-layer capacitors (EDLCs), also referred to as Supercapacitors or Ultracapacitors. These EDLC Supercapacitors/Ultracapacitors are ideal for Supporting Peak Power Requirements In Smart Phones, Tablets and Hand-Held Consumer Products. EDLCs do not have traditional dielectric layers, rather they utilize the phenomenon of storing charge in an “electrical double layer” that is formed at the solid-liquid interface. This advanced technology not only extends Murata’s presence into the energy device market, but complements its current ceramic and polymer technologies found in today’s portable devices.

EDLC Supercapacitors for Smart Phones and TabletsVia optimization of the electro chemical properties and advanced packaging, Murata’s DMD and DME series EDLC Supercapacitors offer a compact part with a high capacitance, high voltage with very low equivalent series resistance (ESR) over a wide temperature range. Additionally, Murata’s EDLCs offer much higher energy storage and power density than any existing conventional capacitor technology. These features make the Murata DMD and DME series ideal for applications requiring burst or pulse loads, like LED flash, audio circuits and power amplifiers. The ability to deliver peak current assistance to the load allows this product to extend battery life between charges.

The DMD and DME EDLC Supercapacitors offer low ESR (as little as 30mΩ at 1kHz) and enable high-current, and high charge-discharge rates. These devices are also eco-friendly as they are fully RoHS-compliant. Furthermore, they can also be incorporated into non portable equipment for applications ranging from back-up to pulse transmission (solid state drives, smart meters and industrial applications). They deliver maintenance-free power storage with a useful life exceeding 100,000 cycles.
