Application Guidelines
Circuit Design: Electrical parameters vary with temperature and frequency. Consider effects on leakage current, capacitance, and ESR. Avoid reverse voltage, over voltage, and exceeding ripple current limits. Use DC bipolar capacitors for circuits with changing polarity. Standard capacitors are not suitable for repeating charge/discharge applications. Pulse current should not exceed 10 times the rated ripple current at 120Hz. For series/parallel connections, consider voltage and ripple current balancing. Mounting considerations include avoiding wiring patterns under capacitors, ensuring correct hole spacing, providing clearance for pressure relief vents, and avoiding high voltage/current wiring near vents. Ensure electrical isolation of the capacitor. Sleeve is for identification, not insulation.
Capacitor Handling: Do not reuse capacitors from used equipment. Discharge transient recovery voltage if necessary. Gradually apply rated voltage with a current limiting resistor for capacitors stored long periods. Avoid using dropped, dented, or crushed capacitors. Verify capacitance, rated voltage, and polarity before insertion. Ensure auto insertion equipment does not stress leads. Observe soldering temperature and time specifications, avoid stress on leads, and do not touch capacitor body with soldering iron. For flow soldering, do not immerse capacitor body. Avoid rapid temperature rises during preheating and resin bonding. Avoid movement of capacitor after soldering. Do not use capacitor as a handle. Avoid striking capacitor after assembly. Circuit boards can be cleaned using suitable solvents, but avoid halogenated, alkali, petroleum-based, xylene, and acetone solvents. Ensure thorough drying. Monitor contamination levels of cleaning solvents. When using adhesives or coating agents, avoid halogenated solvents and chloroprene based polymers.
Precautions for using capacitors: Do not store or use outside rated temperature ranges, in contact with water/oil, high humidity, toxic gases, ozone, radiation, or excessive vibration/shock. Avoid touching terminals due to potential electric shock. Avoid short-circuiting terminals with conductive materials. In case of vent operation, immediately turn off equipment. Avoid contact with escaping electrolyte gas. Flush eyes/skin with water if contact occurs. For long-term storage, recondition capacitors older than one year by applying rated voltage in series with a 1000 resistor for 30 minutes.
Capacitor Disposal: Incinerate after crushing or puncturing the can wall, or dispose of as solid waste, following local laws.
