Aluminum Electrolytic Capacitors - GR Series

The GR Series Aluminum Electrolytic Capacitors are designed for high-performance applications, offering high ripple current and low impedance. They are suitable for use in circuits where machine lifespan is a consideration, and can be manufactured to special specifications upon discussion with R&D personnel for machines with special performance requirements. These capacitors are rated for 105 operation with a lifespan of 2000-4000 hours.

Technical Specifications

Usage Precautions

Circuit Design: Use within rated performance limits. Avoid high temperatures, overcurrent, overvoltage, reverse voltage, AC voltage, and frequent charge/discharge cycles. Ensure proper isolation between capacitor terminals, casing, and circuit. Do not use if casing insulation is insufficient. Avoid contact with water, saltwater, oil, condensation, or environments with harmful gases, direct sunlight, ozone, UV radiation, or radioactive substances. Ensure vibration and shock conditions do not exceed specifications. Select capacitors with a lifespan comparable to the machine's lifespan. For special machine performance requirements, consult R&D for custom capacitors. Ensure proper spacing for capacitor mounting holes and allow space above the safety vent.

Assembly and Installation: Prevent direct contact between capacitor terminals and short circuits. Avoid environments with water, oil, condensation, harmful gases, direct sunlight, ozone, UV radiation, or radioactive substances. Ensure vibration and shock do not exceed specifications. Do not use dropped or deformed capacitors. Ensure correct polarity and terminal spacing. Avoid excessive force with automatic insertion machines. Do not get solder on terminals other than the designated ones. Follow specified welding conditions (temperature, time, frequency). Do not immerse the capacitor body in solder. Avoid other products falling on the capacitor during welding. Ensure the safety valve is facing upwards during vertical installation or the positive terminal upwards during horizontal installation.

Cleaning: Do not clean with detergents. If cleaning is necessary, follow product specifications. Ensure proper management of cleaning agents (conductivity, pH, specific gravity, moisture). After cleaning, do not store in cleaning liquid or sealed containers. Dry with hot air below the maximum operating temperature. Do not use halogen-containing fixing agents or coating agents. When using fixing or coating agents, ensure no solder residue or dirt remains between the PCB and capacitor, and perform drying before application to avoid blocking printing holes.

Maintenance and Disposal: Regular inspections (visual and performance testing) are required for industrial capacitors. In case of safety valve activation, disconnect power immediately. Keep face away from the vent, as hot gas (>100) may be ejected. Flush eyes with water if gas enters. Do not ingest electrolyte; wash skin with soap if contacted. For capacitors with regenerated voltage or long-term storage, discharge through a ~1K resistor. Dispose of capacitors by puncturing or crushing and incinerating, or by handing over to professional recyclers.

Fumigation Treatment: For overseas export, be cautious of corrosion reactions caused by halide fumigants (e.g., potassium bromide). Fumigant should not directly contact the product, and thorough drying is necessary. Consult safety guidelines if fumigant residue or insufficient drying is suspected.

Storage Conditions: Store indoors at 5-30 and below 75% humidity. Do not store in environments that are prohibited during assembly and use.
