Murata Introduces Thin Laminate-Type Energy Device

UMAL Solution Meets Numerous Wireless Sensor Node Demands

Smyrna, GA, – Murata Americas today announced the release of the UMAL, a low-profile high capacity energy device.  Measuring just 2.0 x 14.0 x 21.0 mm, the product was developed to deliver a slim, high-capacity energy source with a maintenance-free extended life cycle.  This makes it ideal for numerous applications, such as wireless sensor nodes, wearables, and back up power solutions.  With that, the UMAL also has charge/discharge and life cycle characteristics superior to conventional secondary batteries.

The UMAL has a nominal voltage of 2.3 VDC, can supply 12 mAh with a maximum discharge current of 120 mA, and is able to withstand load fluctuations. It has a low internal resistance of 200 mOhm and operates over the temperature range of -20 to 70 degrees Celsius.  Given the fast charging/discharging characteristics, the device does not require a peak-assist capacitor. It also has a charge capacity recovery rate of over 90 percent after 5,000 charge/discharge cycles.  Further, the UMAL has a chemically stable composition to mitigate fire and smoke hazards if output terminals short out.

“At Murata, we continually push the envelope to develop advanced solutions that this sophisticated market demands,” said Peter Tiller, General Manager, Component Group, Murata Americas.  “We also have the foresight to determine other applications.  The UMAL is a tremendous example of that as it is also well-suited for wearable designs.”
