• Solder Ability: Meets IEC60068-6-6, with new tin adhering to >90% of immersed lead surface area at 2505 for 20.5sec.
• Resistance to Soldering Heat: Solder bath method at 2605 for 101sec. Capacitance variation within 10%, tan initial specified value, Leakage Current initial specified value, no abnormality in appearance.
• Resistance to Damp Heat (Steady State): 2408h at 402 and 9095% RH according to JIS C 5023. Capacitance variation within 10%, tan initial specified value, Leakage Current initial specified value, no abnormality in appearance.
• Safety Vent Test: Reverse working voltage applied (1A current), vent should operate within 30 minutes. No scattering of leads or foil, no sparks.

Precautions For Use

• Capacitors are polarized; ensure correct polarity to avoid damage. Use bipolar capacitors for unknown or variable polarity circuits.
• Do not exceed the rated working voltage. Recommended usage is 70%-80% of rated voltage for extended life. The sum of DC and peak AC voltage must not exceed the rated voltage.
• Do not exceed the rated ripple current to prevent overheating, deterioration, and shortened lifespan.
• Not suitable for frequent charging and discharging cycles unless specifically designed.
• Ambient temperature significantly impacts lifespan; a 10 increase can halve the life.
• Manual soldering: temperature below 280, time less than 3 seconds. Avoid direct contact between soldering tip and casing.
• Ensure adequate space above the safety vent for effective operation (2mm for 5-16mm, 3mm for 18-35mm, 5mm for 40mm+).
• Do not stress capacitor leads or terminals. Do not forcibly remove capacitors or move PCB boards by lifting the capacitor.
• The aluminum shell is not insulated from the cathode. Avoid placing conductive wires or terminals under the capacitor on the PCB.
• Store in normal temperature, humidity, acid/alkali-free environments, avoiding direct sunlight. For storage over 6 months, consider using a 1K protective resistor during reforming.
• Handle with care to avoid deformation or damage.
• Surge voltage is the maximum DC over-voltage for short periods (approx. 30s in 5min intervals).
• Avoid use in environments with direct contact to water, saltwater, oil, high humidity (>75%), harmful gases, direct sunlight, ozone, UV, radioactive substances, severe vibration/shock, or with halogen-containing fixatives/resins. Confirm compatibility with other fixatives/coatings.
