What are the dimensional tolerances and key specifications of the 32650 cylindrical cell can assembly?
The 32650 assembly has an outside diameter of 32.0 mm, an inside diameter of 31.5 mm, and a height of 68 mm. The bottom thickness is 0.5 mm, and the cap depth is 31.5 mm with a cap height of 5.3 mm. These dimensions are critical for ensuring proper fit and sealing in large-format cylindrical cell assembly.
What are the electrical ratings and performance characteristics of the PPTC cap in this assembly?
The PPTC cap has a non-actuation current of 4.0 A and an actuation current of 8.0 A, with a maximum voltage of 15 V and a maximum current of 40 A. The cap resistance is specified at 7–12 mΩ, which is essential for ensuring reliable overcurrent protection and minimal power loss in the cell.
What materials are used in the 32650 cell can assembly and how do they contribute to cell safety and performance?
The assembly consists of a nickel-plated steel can, a PPTC cap, a PP sealing gasket, and a PET insulating gasket. The nickel-plated steel provides corrosion resistance and structural integrity, while the PPTC cap offers resettable overcurrent protection. The PP sealing gasket ensures a tight seal, and the PET insulating gasket prevents internal short circuits, all contributing to safe and reliable cell operation.
The 32650 Cylindrical Cell Can Assembly is a matched component kit including nickel-plated steel can, PPTC cap, PP sealing gasket, and PET insulating gasket, designed for large-format cylindrical cell assembly with integrated overcurrent protection and defined electrical parameters.
Positive
- Matched component kit: Includes can, PPTC cap, PP sealing gasket, and PET insulating gasket as a pre-coordinated set, ensuring component compatibility and reducing assembly variability in prototype cell builds.
- Integrated PPTC overcurrent protection: PPTC cap provides non-actuation at 4.0 A, actuation at 8.0 A, maximum voltage 15 V, and maximum current 40 A, offering built-in safety and current-limiting capability for the cell assembly.
Trade-offs
- PPTC cap series resistance: The cap resistance of 7–12 mΩ adds a fixed series impedance to the cell, which can increase internal resistance and reduce power delivery efficiency in high-drain applications.
- Fixed 50-set packaging quantity: Supplied as 50 complete assemblies per pack, which may be excessive for early-stage prototyping or small-scale tests, requiring bulk purchase for initial evaluation.
