Description

THOR-103048 concentrates 1500mAh into a short, narrow 10 × 30 × 48mm bare-cell envelope. Compared with THOR-424272, it reduces width by 12mm and length by 24mm, but increases nominal thickness from 4.2mm to 10mm. This makes THOR-103048 the compact-footprint choice when enclosure depth is available. THOR-103140 keeps the same capacity and 10mm thickness in a slightly wider but 8mm shorter format.

The 10 × 30 × 48mm value is the nominal bare-cell envelope. The current PCM-equipped drawing is approximately 10 × 30 × 50mm. PCM layout, insulation, lead exit, connector position and wire bend radius must be included in the finished cavity, then verified with the approved drawing and samples.

At 3.7V nominal and 1500mAh, THOR-103048 stores 5.55Wh. Actual runtime depends on device load, regulator efficiency, cutoff voltage, duty cycle, temperature and aging. Capacity and compact geometry do not establish high-rate performance, so validate continuous and peak demand before sample approval.

THOR-103048 Engineering & Fit Questions

How does THOR-103048 differ from THOR-424272?

THOR-103048 uses a compact 10 × 30 × 48mm envelope. THOR-424272↗ has the same 1500mAh capacity but spreads it across a much thinner 4.2 × 42 × 72mm cell. Select between compact plan area and lower thickness according to the enclosure.

Are 10 × 30 × 48mm the protected-pack dimensions?

No. They are nominal bare-cell dimensions. The current PCM-equipped drawing is approximately 10 × 30 × 50mm, and connector, insulation, lead exit and wire routing can require more clearance. Validate the final cavity with production-intent samples.

What must be checked before approving THOR-103048 for a device?

Confirm the finished-pack envelope, connector and polarity, wire routing, continuous and peak load, regulator efficiency, system cutoff voltage, charge method, operating temperature and expected duty cycle. The 1500mAh rating alone does not confirm runtime or pulse-load suitability.

3.7V 1500mAh Lithium Polymer (LiPo) Battery with Connector | THOR-103048

THOR-103048 is a 3.7V 1500mAh LiPo pouch cell with 5.55Wh nominal energy and a compact 10 × 30 × 48mm bare-cell envelope. It exchanges the thin, broad shape of THOR-424272 for a much shorter and narrower footprint, making it useful when plan area is constrained but 10mm cell depth is available. Final pack size and load suitability require engineering validation.

Typical Applications — THOR-103048

Compact Handheld Scanners & Terminals — PrimaryThe short 30 × 48mm footprint can suit handheld scanner or terminal cavities that have limited plan area but can accommodate 10mm nominal cell depth. Confirm display, processor, radio and peak-load requirements.

Portable Data-Acquisition & Test ModulesTHOR-103048 can support compact data-acquisition or test modules where a short battery footprint is more important than minimum thickness. Validate sensing duty cycle, storage, communications and finished-pack fit.

Wireless Measurement DevicesThe 5.55Wh capacity may suit wireless measurement devices with periodic sensing and communication after standby drain, transmit pulses, cutoff voltage and enclosure clearance are reviewed.
