General Information & Precautions
- Maximum RMS Ripple Current: Values are tested at +105C, 100kHz. Adjustments are necessary for different operating temperatures and frequencies using provided coefficients.
- Working Voltage: Ensure applied voltage does not exceed the rated voltage. Peak voltage, including DC voltage and ripple, must not exceed the rated voltage.
- Insulation: Standard types have a PET sleeve for marking. For insulated cases, special designs are recommended.
- Soldering: Avoid excessive temperature or time to prevent sleeve damage. Maintain a small distance between the capacitor and the PCB.
- Safety Vent: Capacitors (10mm) feature a bottom vent for pressure release under abnormal conditions.
- High Altitude: Suitable for transportation in temperatures from -40 to +105 and altitudes up to 200,000 feet.
- Cleaning Agents: Avoid halogenated organic solvents to prevent internal corrosion.
