Description
Model AS084546 – Ultra-Thin LiPo Bare Cell
Voltage: 3.7V (Nominal) | Capacity: / | Size: 46.5×45.5×0.9mm

The AS084546 represents the pinnacle of thin-profile energy storage. As a specialized Lithium Ion Polymer Battery, it is designed to fit into devices where every millimeter counts. Its unique 0.9mm thickness allows it to be integrated into credit-card-sized electronics or slim medical patches where traditional cylindrical or thicker pouch batteries cannot fit.
Despite its slim profile, it maintains the standard 3.7V nominal voltage and offers stable discharge performance suitable for low-power IoT devices. The battery features a robust black casing for enhanced durability and protection against minor physical stress. Whether you are developing a smart ID card, a thin-film sensor, or a compact Bluetooth tracker, the AS084546 provides the essential power density you need in a form factor that disappears into your design.
