THOR-902050 provides 900mAh in a narrow, elongated 9 × 20 × 50mm bare-cell envelope. THOR-902540 keeps the same capacity and thickness but uses a shorter, wider 25 × 40mm footprint. If lower thickness matters more than minimum width, THOR-752845 provides 900mAh in a 7.5 × 28 × 45mm format.

The 9 × 20 × 50mm value is the nominal bare-cell envelope, not a guaranteed finished-pack size. PCM layout, insulation, lead exit, connector and wire routing can add space around the cell. Confirm the production-intent drawing, mating connector and enclosure clearance before sample approval.

At 3.7V nominal and 900mAh, THOR-902050 stores 3.33Wh. Runtime depends on the device load profile, regulator efficiency, cutoff voltage, duty cycle, temperature and aging. Capacity and dimensions do not establish high-discharge capability; validate continuous and peak demand with the actual system.

• Stable 3.7 V nominal output for reliable power delivery
• Long cycle life — typically several hundred cycles, cost-efficient
• Built-in protection: overcharge, over-discharge, short-circuit
• Custom size, capacity, connector & PCM/BMS
• UN38.3 / MSDS ready; CE, KC, ROHS on request
