Technical Specifications

Usage Precautions

Circuit Design

• Use within rated performance and avoid high temperature, overcurrent, overvoltage, reverse voltage, AC voltage, and rapid charge/discharge circuits.
• Select capacitors with a lifespan comparable to the machine.
• Ensure complete isolation between capacitor terminals, casing, and circuit.
• Avoid use in environments with direct contact to water, saltwater, oil, condensation, or harmful gases.
• Do not expose to direct sunlight, ozone, UV rays, or radioactive substances.
• Avoid environments with vibration and shock exceeding specified limits.
• Ensure proper spacing for capacitor installation, including adequate space above the safety vent and avoiding placement of other components or wiring near the vent.
• Avoid placing heat-generating components near the capacitor.
• For double-sided PCBs, avoid mounting capacitors over unnecessary holes.
• Ensure current and voltage balance for parallel and series connections, respectively.

Assembly and Installation

• Do not allow terminals to directly contact each other or for conductive materials to cause short circuits.
• Avoid contact with water, oil, or condensation.
• Do not expose to sunlight, ozone, UV rays, or radiation.
• Avoid environments with harmful gases.
• Ensure vibration and shock do not exceed specified limits.
• Do not use capacitors that have been dropped, deformed, or removed from the machine for inspection/testing unless reconditioned.
• Ensure terminal spacing matches PCB hole spacing.
• Avoid excessive force from automatic insertion machine grippers.

Soldering

• Prevent solder from adhering to areas other than terminals.
• Adhere to specified soldering temperature, time, and number of times.
• Do not immerse the capacitor body in solder solution.
• Avoid other products falling and contacting the capacitor during soldering.

Post-Soldering Handling

• Avoid mechanical stress such as tilting or twisting.
• Prevent the capacitor from hitting other PCBs or being hit by other objects.

Cleaning

• Do not clean capacitors with cleaning agents unless necessary and within specified limits.
• When cleaning is necessary, manage cleaning agent contamination (conductivity, pH, specific gravity, moisture) and ensure thorough drying with hot air to prevent residue.
• Do not use halogen-containing fixatives or coating agents.
• When using fixatives or coating agents, ensure no solder residue or dirt remains between the PCB and capacitor, and dry thoroughly to prevent clogging of printed holes.

Storage Conditions

• Store indoors at temperatures between 5-30C and humidity below 75%.
• Do not store in environments prohibited for assembly and use.

Disposal

• Puncture or crush and incinerate.
• Alternatively, hand over to specialized waste recycling personnel.

Accident Handling

• If the safety vent opens during assembly, cut off the main power or unplug.
• Keep face away from the vent when it operates, as hot gas (>100C) may be ejected. Flush eyes with water if gas enters, do not taste electrolyte, and wash skin with soap if electrolyte splashes.

Fumigation Treatment

• Be cautious with fumigation using halides like potassium bromide for overseas export, as it may cause corrosion due to halide ions.
• Ensure fumigant does not directly contact electronic products and allow for thorough drying.
