Description

THOR-602530 provides 500mAh in a short 6 × 25 × 30mm bare-cell envelope. THOR-602535 keeps the same thickness, width and capacity but adds 5mm of length. THOR-503035 reduces thickness to 5mm at the same capacity, but requires a wider and longer 30 × 35mm footprint. Choose THOR-602530 when the 25 × 30mm plan area is the binding constraint.

The 6 × 25 × 30mm value is the nominal bare-cell envelope, not a guaranteed finished-pack dimension. PCM placement, insulation, connector body, lead exit and wire bend radius can require additional clearance. Confirm the production-intent assembly before enclosure approval.

At 3.7V nominal and 500mAh, THOR-602530 stores 1.85Wh. Runtime depends on standby drain, active duty cycle, regulator efficiency, cutoff voltage, temperature and aging. Capacity and geometry do not establish current capability; validate continuous and peak demand with the approved cell, PCM and harness.

THOR-602530 Engineering & Fit Questions

How does THOR-602530 compare with THOR-602535 and THOR-503035?

THOR-602535↗ keeps the same 6mm thickness, 25mm width and 500mAh capacity but is 5mm longer. THOR-503035↗ reduces thickness to 5mm at the same capacity but requires a 30 × 35mm footprint.

Are 6 × 25 × 30mm the finished THOR-602530 dimensions?

No. They are nominal bare-cell dimensions. PCM placement, insulation, connector body, lead exit and wire routing can increase the finished envelope, so confirm the production-intent assembly before enclosure release.

How should THOR-602530 runtime and load suitability be checked?

Use 1.85Wh as the nominal energy starting point, then measure standby drain, active duty cycle, pulse load, regulator losses, cutoff voltage and temperature effects. Validate the final protection and harness before sample approval.

Typical Applications — THOR-602530

Short-Body Wireless Sensor Modules — PrimaryThe 25 × 30mm plan area can suit compact sensor modules where battery length is tightly constrained. Confirm standby drain, sample interval, radio bursts and the finished-pack envelope.

Compact Handheld Control ModulesTHOR-602530 may suit small controllers or remote modules designed around a short battery bay. Validate button, radio and indicator duty cycles together with connector clearance.

Rechargeable Identification & Access ModulesThe 1.85Wh nominal energy can support compact identification or access electronics when reader, display and communication loads are measured in the final device.
