UMAL201421A012TA01

Sm a l l E n e r gy D e v i c e L a m i n a t e t y p e ( UM A L ) NRND: Not recommended for new design. Instead, please use UMAL201421A012TA02 for new design. Rechargeable battery having long cycle life High rate charge/discharge is available. Advantages ① High rate charge/discharge 200mohm low ESR and high rate(10C,120mA) enabled by optimizing materials and structure ② High safety No thermal runaway occurs because of its low capacity and chemically stable materials. ③ Long cycle life Charge (capacity) recovery is over 90% even after 5K cycles. It can realize maintenance free design Applications & Benefits 1. Energy Harvesting Systems 2. Backup ・Charge/Discharge in Wide Input/Output Range ・Long working time due to Low Leakage Current ・Quick start without pre-charging due to Low Leakage Current ・Enables Maintenance Free ・Can backup system during replacing main battery ・Long backup time over 30sec ・High power discharge is available Power f ailure ・Long cycle life Power failure Unstable input Power Harvester Power Load UMAL UMAL PS Power Supply UMA UMA Time Time Application Example:  Solar battery charger equipment  Sensor node with wireless sensor network in combination with micro and macro energy harvesting systems Load Application Example:  Handy terminal / barcode reader  POS (payment terminals, etc.)  Emergency call or transmitter (medical equipments such as nurse call, industrial equipments using ISM band, etc.)  Other battery powered equipments  3. Small power equipment power ・Can be charged with High Input(10C,120mA) High input ・Quick start due to high Input ・Permanent use due to long cycle life UMAL ・High safety due to low capacity Application Example:  PC accessory (Wireless mouse, etc.)  Wearable equipment For more details, please visit our website.
