Application Guidelines

Circuit Design Considerations:

• Electrical parameters vary with temperature and frequency.
• Avoid reverse voltage, charge/discharge applications, over voltage, and excessive ripple current.
• Capacitors in parallel may experience unbalanced ripple current loads.
• Capacitors in series may experience voltage imbalances due to leakage current differences.

Capacitor Mounting Considerations:

• Avoid wiring patterns between the capacitor and the circuit board.
• Ensure correct hole spacing to avoid lead stress.
• Provide clearance for pressure relief vents.
• Avoid locating high voltage wiring above pressure relief vents.
• Avoid circuit board runs under the capacitor.

Capacitor Handling Techniques:

• Do not reuse capacitors from used equipment.
• Transient recovery voltage may require discharge.
• Capacitors stored long-term may have increased leakage current, requiring reconditioning.
• Avoid using dropped, dented, or crushed capacitors.
• Verify correct capacitance, rated voltage, and polarity before insertion.
• Avoid stressing capacitor leads during insertion and soldering.
• Observe soldering temperature and time specifications.
• Avoid immersing the capacitor body into the solder bath.
• Avoid movement of the capacitor after soldering.
• Do not use the capacitor as a handle.
• Avoid striking the capacitor after assembly.

Circuit Board Cleaning:

• Use suitable cleaning solvents, rinse, and dry thoroughly.
• Avoid specific solvent groups (halogenated, alkali, petroleum-based, xylene, acetone) unless specified.
• Monitor contamination levels of cleaning solvents.

Mounting Adhesives and Coating Agents:

• Avoid materials containing halogenated solvents or chloroprene based polymers.
• Dry thoroughly after application.

Precautions for using capacitors:

• Do not store or use outside rated temperature ranges.
• Avoid contact with water, salt water, oil, high humidity, toxic gases, ozone, radiation, UV rays, excessive vibration, or shock.
• Avoid touching terminals due to electric shock risk.
• Avoid short-circuiting terminals with conductive materials.

Emergency Procedures:

• If pressure relief vent operates, immediately turn off equipment and disconnect power.
• Avoid contact with escaping electrolyte gas. Follow first aid procedures for eye, mouth, or skin contact.

Long Term Storage:

• Leakage current increases with storage time. Recondition capacitors stored for over one year by applying rated voltage in series with a 1000 resistor for 30 minutes.
• Products with date codes over eighteen months should be returned for confirmation.

Capacitor Disposal:

• Incinerate after crushing or puncturing the can wall.
• Dispose of as solid waste, following local laws.
