UMAC040130A003TA01 Datasheet, PDF (1/3 Pages) –

Small Energy Device
Cylinder type (UMAC)
RoHS
Hand
REACH Soldering
Only
Rechargeable battery having long cycle life
High rate charge/discharge is available.
Advantages
① High rate charge/discharge
800mohm low ESR and high rate (10C, 30mA) 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 80% even after 3000 cycles. It can realize maintenance free design.
④ Compact and lightweight
Package size: φ4 x 12mm, Weight：0.29g
