Important Notes and Characteristics

General Information:

• Maximum RMS Ripple Current: Specified at +105C, 100KHz. Adjustments for different temperatures and frequencies are necessary using provided coefficients. Verification methods follow JIS-C-5101-1(2010) No.: 4.23. Self-generated heat should be within 5C if ripple current is difficult to measure.
• Working Voltage: Ensure applied voltage does not exceed the rated voltage. Peak voltage (DC + ripple) must not exceed the rated voltage.
• Insulation: Standard capacitors have a vinyl sleeve for marking. For insulated aluminum cases, special types are recommended.
• Soldering: Avoid excessive soldering temperature or time to prevent sleeve shrinkage. Solder on the reverse of the PC board. Maintain a distance between the capacitor and the circuit board to prevent sleeve damage.
• Vent: Capacitors (10mm) have a safety vent at the bottom to release internal pressure during unsafe usage.
• High Altitude: Capacitors can withstand transportation at -55~105C and altitudes up to 20,000 feet.
• Cleaning Agents: Avoid halogenated organic solvents, as they may penetrate and cause corrosion.

• Solderability: Sn96.5%Ag3%Cu0.5% solder at 2455C for 2.00.5S. New solder coverage > 95%.
• Resistance to Soldering Heat: Specific profiles for different sizes (T1, t1, Peak temp). Reflow acceptable twice.
• Vent Test (for applicable products): Reverse voltage 80V. No explosion, flash, flame, spark, or fire when vent operates.
