Handling, Safety & Standard Packaging
Technical handling guidelines, mandatory safety boundaries, and export packaging specifications applicable across all 4.0V, 3.6V, and 2.7V families. Soldering profiles and packing quantities for individual parts are governed by their respective engineering datasheets.
01 Assembly & Handling Notes
- Soldering Process: +350 °C for 4–5 s maximum with manual soldering iron; manual soldering is generally not recommended for volume production. Adhere strictly to the recommended reflow profile.
- PCB Cleaning: Avoid board-level aqueous/solvent washing. If cleaning is unavoidable, verify solvent chemical compatibility with the aluminium case and rubber sealing plug beforehand.
- Lead Polarity: Radial pins are polarized — the longer lead is Positive (+). Verify PCB silkscreen alignment and polarity markings prior to automated insertion.
- Handling Rules: Zero reverse voltage, zero overvoltage, no mechanical lead bending without proper jig support, and no disassembly.
02 Mandatory Safety Boundaries
- Intrinsic Safety: Lithium-ion capacitor chemistry is inherently non-volatile and does not exhibit classic thermal runaway under UL 810A testing.
- Voltage Safeguards: Strictly operate within rated upper working voltage (e.g. 4.0V max); never exceed specified peak surge voltages under dynamic transient spikes.
- Thermal Limits: Deploy strictly within datasheet operating temperatures; isolate cells from adjacent power semiconductor heat sinks.
- Storage Protocols: Store in a cool, dry room environment (<30°C, <60% RH). For long-term warehousing (>6 months), maintain cells within the recommended storage voltage range.
03 Packaging & Logistics Standards
- Standard Bulk Packing: Radial cells bulk packaged in moisture-proof anti-static bags. Ø4–10 mm: 2,400 pcs/bag; Ø12–24 mm: packaged per specific cell diameter.
- SMT Reel / Tray Options: Tape & reel, extruded tube, or customized thermoformed trays available on request to interface directly with customer pick-and-place lines.
- Laser Product Marking: High-contrast laser/ink marking indicates manufacturer, capacitance (F), voltage (V), part model, and polarity indication.
- International Shipping: Certified UN38.3 non-hazardous cargo compliance; shipped globally with Dangerous Goods / Air Transport Appraisal reports and MSDS.
