Technical Specifications

Usage Precautions

1. Circuit Design

• Use within the rated performance range specified in the product datasheet. Avoid: high temperature, overcurrent, overvoltage, reverse or AC voltage, and circuits with frequent rapid charge/discharge.
• Select capacitors with a lifespan comparable to the machine's lifespan.
• Ensure complete isolation between capacitor casing, auxiliary terminals, positive/negative terminals, and the circuit.
• If the capacitor sleeve's insulation is insufficient, do not use it in applications with specific insulation requirements.
• Avoid environments with direct contact with water, saltwater, oil, condensation, or harmful gases (sulfides, H2SO3, HNO3, CL2, ammonia).
• Avoid environments with direct sunlight, O3, UV radiation, or radioactive substances.
• Avoid environments with vibration and shock exceeding specified limits.
• Ensure correct spacing between capacitor terminals and PCB holes.
• Ensure sufficient space above the capacitor's safety vent.
• Avoid placing wiring or other components above the safety vent.
• Avoid placing other wiring near the capacitor on the PCB.
• Avoid placing heat-generating components around the capacitor or on the PCB.
• Ensure temperature and frequency changes do not affect electrical performance.
• On double-sided PCBs, avoid installing capacitors over unnecessary holes or vias.
• Ensure current equalization when connecting multiple capacitors in parallel.
• Ensure voltage equalization when connecting multiple capacitors in series.

2. Component Installation

• Do not allow capacitor terminals to directly contact each other or other conductors, which could cause a short circuit.
• Confirm the environment at the capacitor's installation location: avoid contact with water, oil, condensation, direct sunlight, O3, UV, radiation, or harmful gases. Avoid vibration and shock exceeding specified limits.
• When installing, do not reuse capacitors that have been removed from equipment for inspection or testing.
• Discharge capacitors with a regenerative voltage using approximately a 1K resistor.
• Discharge capacitors stored for extended periods using approximately a 1K resistor.
• Confirm specifications (capacitance, rated voltage, polarity) before installation.
• Do not use dropped capacitors.
• Do not install deformed capacitors.
• Ensure capacitor terminal spacing matches PCB hole spacing.
• Avoid excessive force from automatic insertion machine grippers.

3. Soldering

• Ensure solder does not adhere to areas other than the terminals.
• Follow specified soldering conditions (temperature, time, number of times).
• Do not immerse the capacitor body in the solder solution.
• Ensure other products do not fall and hit the capacitor during soldering.

4. Post-Soldering Treatment

• Ensure no mechanical stress is applied to the capacitor after soldering (e.g., tilting, twisting, or contact with other components).
• Do not clean capacitors with cleaning agents. If cleaning is necessary, perform it within the limits specified in the datasheet.
• When cleaning is required, verify cleaning agent management (conductivity, pH, specific gravity, moisture) and ensure no cleaning fluid residue remains after drying with hot air (below maximum operating temperature).
• Do not use halogen-containing fixing agents or resin coating agents.
• When using fixing or coating agents, ensure no solder residue or dirt remains between the PCB and capacitor. Dry thoroughly before application and ensure no clogging of through-holes.
• For bolt-type products, install vertically with the pressure valve facing upwards, or horizontally with the pressure valve or positive terminal facing upwards.

5. Maintenance and Inspection

Capacitors in industrial and commercial equipment require regular inspection, including visual checks and performance testing.

6. Accidental Situations

• If the capacitor's safety vent opens during assembly, cut off the main power or unplug the power cord.
• When the safety vent operates, hot gas exceeding 100 may be ejected. Keep face away. If gas enters eyes, rinse immediately with water. Do not taste the electrolyte. If electrolyte contacts skin, wash with soap.

7. Fumigation Treatment

When exporting electronic products containing capacitors overseas, fumigation with halides like potassium bromide may cause corrosion due to halide ions. Take precautions. Fumigant should not directly contact the product, and thorough drying is necessary. If fumigant residue or insufficient drying is suspected, verify safety beforehand.

8. 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.

9. Disposal

• Dispose of waste capacitors by:
• a) Puncturing or crushing and then incinerating.
• b) Handing over to specialized waste recyclers if incineration is not performed.

Part Number System Explanation

The part number system is structured to encode various specifications of the capacitor, including capacitance, tolerance, voltage, size, series, and other features. For example, GR108M080K30RR0VZ2FP0 indicates:

• GR: Series (e.g., GR Series +105, High Ripple Current, Low Impedance)
• 108: Capacitance Code (10 x 10^8 uF = 1000 uF)
• 080: Voltage Code (80V)
• K: Tolerance Code (10%) - Note: The provided example C47881 has 1000uF/80v, which aligns with GR108M080K30RR0VZ2FP0. The tolerance for 'K' in the chart is 10%, but the specification sheet lists 20% for capacitance. This discrepancy should be noted.
• 30: Case Size Diameter (30mm)
• RR0: Special Code / Background Code
• VZ2FP0: Other Codes (Sleeve Material, Shape, etc.)

Features

• Low Impedance for high frequency.
• Long life: 2000~3000 hours at 105.
