Description

Choose THOR-603048 when a 30 × 48mm bare-cell footprint is available and the design needs 900mAh without exceeding 6mm nominal cell thickness. Within the same footprint family, THOR-503048 is 1mm thinner at 800mAh, while THOR-703048 offers 1000mAh at 7mm. This model sits between them when enclosure depth and nominal capacity must be balanced.

Check the usable battery cavity rather than relying on the bare 6.0 × 30 × 48mm cell dimensions. The existing PCM-equipped drawing indicates approximately 6.0 × 30 × 50mm, but the final assembly depends on PCM position, insulation, connector body, lead-wire exit, and bend radius. Confirm polarity and allow for manufacturing tolerance and normal pouch-cell expansion before freezing the enclosure.

At 3.7V nominal, 900mAh corresponds to 3.33Wh. Real device runtime depends on continuous and pulse load, regulator efficiency, cutoff voltage, wireless or sensor duty cycle, operating temperature, and cell aging. For motor-driven or printhead loads, check peak current and voltage sag against the approved cell, PCM, wires, and connector rather than assuming that capacity alone proves suitability. Confirm the charging profile, optional NTC needs, harness details, and target runtime against the final engineering drawing before sample approval.

THOR-603048 Engineering & Fit Questions

What are the bare-cell and finished dimensions of THOR-603048?

The nominal bare-cell envelope is 6 × 30 × 48mm. The current PCM-equipped drawing shows approximately 6 × 30 × 50mm. Confirm PCM position, insulation, connector body, lead-wire exit, bend radius and manufacturing tolerance against the production-intent drawing.

How does THOR-603048 fit between THOR-503048 and THOR-703048?

THOR-503048↗ is the thinner 5mm, 800mAh option in the same 30 × 48mm nominal footprint, while THOR-703048↗ increases thickness to 7mm and capacity to 1000mAh. THOR-603048 occupies the 6mm, 900mAh middle position.

Can THOR-603048 be selected for audio transmitters or compact label printers from capacity alone?

No. Capacity alone does not establish application suitability. Wireless transmitters, motors and print heads can create peak-current and voltage-sag requirements that must be checked against the approved cell, PCM, wires and connector in the actual duty cycle.

What should be confirmed before enclosure and harness release?

Confirm the final pack envelope, connector family and polarity, wire gauge and length, cable exit, optional NTC, charging profile, continuous and peak load, operating temperature and the target runtime measured in the actual device.
