Usage Precautions

1. Circuit Design

• Use capacitors within the rated performance range as per product sample specifications. Avoid conditions like: high temperature (> max operating temp), overcurrent (> rated ripple current), overvoltage (> rated voltage), reverse or AC voltage, and circuits with frequent rapid charge/discharge.
• When designing circuits, select capacitors with a lifespan comparable to the machine's lifespan. For special machine performance requirements, consult with R&D for custom specifications.
• Ensure complete isolation between capacitor casing, terminals, and the circuit.
• If the capacitor sleeve insulation is insufficient for specific requirements, do not use.
• Avoid using capacitors in environments with direct contact with water, saltwater, oil, or in condensing conditions. Also avoid environments with harmful gases (sulfides, H2SO3, HNO3, CL2, ammonia), direct sunlight, ozone, UV radiation, radioactive substances, or excessive vibration and shock.
• When designing capacitor installation, ensure correct polarity spacing on the PCB, sufficient space above the safety vent, and avoid placing other components or wiring directly above the vent. Minimize wiring and heat-generating components around the capacitor.
• Consider temperature and frequency variations that might affect electrical performance. For double-sided PCBs, avoid unnecessary holes near capacitor mounting points. Ensure current and voltage equalization for parallel and series connections, respectively.

2. Component Installation

• Ensure terminals do not touch each other or cause short circuits.
• Verify the installation environment: avoid contact with water/oil, condensation, direct exposure to sunlight, ozone, UV, or radiation. Avoid environments with harmful gases or excessive vibration/shock.
• After soldering, ensure no mechanical stress is applied to the capacitor (tilting, twisting, impact).
• Do not wash capacitors with cleaning agents. If cleaning is necessary, adhere to product specification limits and ensure proper drying afterwards to prevent residual cleaning fluid.
• Do not use halogen-containing fixatives or coating agents. If using fixatives/coating agents, ensure no residue or dirt remains between the PCB and capacitor, and perform adequate drying.
• For screw-type capacitors, ensure the pressure valve faces upwards during vertical installation, or the valve/positive terminal faces upwards during horizontal installation.

3. Assembly and Use

• During assembly, prevent direct contact between capacitor terminals and avoid short circuits.
• Check the assembly environment: avoid water/oil contact, condensation, direct exposure to sunlight, ozone, UV, or radiation. Avoid harmful gas environments and excessive vibration/shock.
• Ensure terminals do not touch each other and avoid short circuits.
• When testing electrical performance, do not reuse capacitors that have been removed from the machine or have been energized.
• Discharge capacitors with a regenerative voltage using a ~1K resistor.
• Discharge capacitors stored long-term using a ~1K resistor under pressure.
• Verify specifications (capacitance, voltage) and polarity before installation.
• Do not drop capacitors; do not use dropped capacitors.
• Do not install deformed capacitors.
• Ensure the spacing between capacitor terminals matches the PCB hole spacing.
• Avoid excessive force from automatic insertion machine grippers.
• When soldering, ensure solder does not adhere to areas other than the terminals. Follow specified temperature, time, and number of cycles for soldering. Do not immerse the capacitor body in the solder solution. Avoid other products falling and hitting the capacitor during soldering.

4. Regular Inspection

Capacitors used in industrial and commercial applications require regular inspections, including visual checks and performance testing.

5. Accidental Situations

• If a capacitor's safety vent opens during assembly, disconnect the main power or unplug the power supply.
• When the safety vent operates, hot gas (>100) may be ejected. Keep face away. If gas enters eyes, flush immediately with water. Do not ingest electrolyte. If electrolyte contacts skin, wash with soap.

6. Fumigation Treatment

When exporting products containing capacitors overseas, be cautious of fumigation treatments using halides like potassium bromide, which can cause corrosion due to halide ions. Ensure fumigant does not directly contact products and allow for thorough drying. Verify safety if fumigant residue or insufficient drying is suspected.

7. Storage Conditions

• Store indoors at temperatures between 5-30 and humidity below 75%.
• Do not store in environments or conditions that are prohibited during assembly and use.

8. Disposal

Dispose of (waste) capacitors by either: punching holes or crushing them before incineration, or handing them over to specialized waste recyclers if incineration is not performed.
