Description

THOR-501227 is the middle geometry in the 5mm-thick micro-cell ladder, providing 130mAh in a 5 × 12 × 27mm bare-cell envelope. THOR-501125 is 1mm narrower and 2mm shorter with 100mAh. THOR-501525 provides 150mAh in a 15mm-wide, 25mm-long format, trading width for a shorter length and 20mAh more capacity.

The 5 × 12 × 27mm value is the nominal bare-cell envelope. The current PCM-equipped drawing is approximately 5 × 12 × 29mm. PCM position, insulation, connector height, lead exit and wire bend radius can materially affect the finished geometry in a micro enclosure.

At 3.7V nominal and 130mAh, THOR-501227 stores approximately 0.48Wh. Actual runtime depends on standby current, active duty cycle, radio or sensor pulses, regulator efficiency, cutoff voltage, temperature and aging. Validate peak demand and voltage sag with the intended electronics.

THOR-501227 Engineering & Fit Questions

When should I choose THOR-501227 instead of THOR-501125 or THOR-501525?

Choose THOR-501227 when 130mAh is useful and the cavity can accept 12 × 27mm. THOR-501125↗ is smaller at 11 × 25mm with 100mAh, while THOR-501525↗ provides 150mAh in a wider but shorter 15 × 25mm footprint.

Are 5 × 12 × 27mm the protected-pack dimensions?

No. They are nominal bare-cell dimensions. The current PCM-equipped drawing is approximately 5 × 12 × 29mm, and connector height, insulation, lead exit and wire routing can require additional clearance.

How should a 130mAh design be runtime-tested?

Test the real standby current, active duty cycle, pulse magnitude and duration, regulator efficiency, system cutoff voltage, temperature range and aging allowance. Runtime calculations based only on 130mAh will not capture voltage sag or conversion losses.

3.7V 130mAh Lithium Polymer (LiPo) Battery with Connector | THOR-501227

THOR-501227 is a 3.7V 130mAh LiPo pouch cell with approximately 0.48Wh nominal energy and a 5 × 12 × 27mm bare-cell envelope. It occupies the middle of the THOR-501125 / 501227 / 501525 micro-cell ladder, adding capacity with a modest footprint increase while remaining narrower than THOR-501525. Final pack and pulse-load requirements must be verified.

Typical Applications — THOR-501227

Compact Wearable Control Modules — PrimaryThe 5 × 12 × 27mm geometry can suit wearable control modules that need more capacity than a 100mAh-class cell without moving to a 15mm-wide format. Confirm duty cycle, enclosure clearance and mechanical protection.

Wireless Sensor Nodes & Smart TagsTHOR-501227 may suit low-duty sensor nodes or smart tags after standby drain, radio pulses, reporting interval and finished-pack dimensions are validated.

Compact Audio & Accessory ElectronicsThe cell can be considered for compact audio or accessory electronics when pulse demand, connector placement, thermal behavior and charge method are verified.
