Product Overview

The SAMXON GF Series Aluminum Electrolytic Capacitors are designed for general-purpose electronic equipment applications. These polar, foil-type capacitors meet IEC60384 standards and are constructed with an aluminum case, sealed with end seal rubber, and enclosed in a PET vinyl sleeve. They are suitable for continuous operation across a specified temperature range and offer reliable performance with features like safety vents for larger diameters.

Application Guidelines - Circuit Design

• Operating Temperature and Frequency: Electrical parameters vary with temperature and frequency. Higher temperatures increase leakage current and capacitance, decrease ESR. Lower temperatures decrease leakage current and capacitance, increase ESR. Higher frequencies decrease capacitance and impedance, increase tan. Lower frequencies increase ESR, leading to ripple current generated heat.
• Operating Temperature and Life Expectancy: Refer to "Life calculation of aluminum electrolytic capacitor" file.
• Common Application Conditions to Avoid: Reverse Voltage, Repeating Charge/Discharge Applications, Over voltage, Ripple Current exceeding specified values.
• Using Two or More Capacitors in Series or Parallel: Parallel connection requires careful wiring to balance ripple current loads. Series connection requires voltage divider shunt resistors to prevent voltage imbalances due to leakage current differences.
• Capacitor Mounting Considerations: Avoid wiring patterns under mounted capacitors on double-sided boards. Ensure proper hole positioning and spacing to prevent lead stress. Allow clearance for pressure relief vents (minimum clearances: 2mm for 6.3~16mm, 3mm for 18~35mm, 5mm for 40mm or greater). Ensure a hole in the circuit board under seal mounted vents. Avoid high voltage/current wiring near pressure relief vents. Avoid circuit board runs under the capacitor. For screw terminal capacitors, do not orient with the screw terminal side facing downwards. Tighten screws within specified torque range.
• Electrical Isolation: Completely isolate capacitor cathode from case (except B types) and anode terminal from other circuit paths. Isolate extra mounting terminals from anode, cathode, and other circuit paths.
• Product Endurance: Sample is the standard.
• Load or Shelf Life Test: Collect date code within 6 months products of sampling.
• Capacitor Sleeve: For marking and identification; not for electrical insulation. May split/crack with solvents and high temperatures.
• Safety Precautions: Plan for worst-case failure modes (short/open circuits). Provide protection circuits and devices. Design redundant circuits where possible.

Capacitor Handling Techniques

• Considerations Before Using: Capacitors have finite life; do not reuse from used equipment. Transient recovery voltage may require discharge with a resistor (approx. 1k). Long-term storage may increase leakage current; recondition with rated voltage in series with a 1k resistor. Avoid using dropped, dented, or crushed capacitors.
• Capacitor Insertion: Verify capacitance, rated voltage, and polarity. Verify hole spacing to avoid terminal stress. Ensure auto-insertion equipment does not stress leads at the seal. Avoid excessive mounting pressure on chip types.
• Manual Soldering: Observe temperature and time specifications (do not exceed 400C for 3 seconds). Avoid stress on lead wires at the seal. Avoid excessive stress during reinsertion. Do not touch capacitor with soldering iron tip.
• Flow Soldering: Do not immerse capacitor body into solder bath. Observe proper soldering conditions. Prevent other parts from touching the capacitor during soldering.
• Other Soldering Considerations: Avoid rapid temperature rises during preheat and resin bonding to prevent sleeve cracking. For heat curing, do not exceed 150C for a maximum of 2 minutes.
• Capacitor Handling after Solder: Avoid moving capacitor after soldering to prevent lead wire stress. Do not use capacitor as a handle. Avoid striking capacitor after assembly.
• Circuit Board Cleaning: Boards can be immersed or ultrasonically cleaned (up to 5 minutes, 60C max). Rinse and dry thoroughly. Avoid ozone-depleting agents. Avoid halogenated solvents (except solvent-resistant types), alkali solvents, petroleum-based solvents, xylene, and acetone unless specified. Thorough drying is required. Monitor contamination levels.
• Mounting Adhesives and Coating Agents: Avoid materials containing halogenated solvents or chloroprene-based polymers. Dry thoroughly after application.

Precautions for Using Capacitors

• Environmental Conditions: Do not store or use outside rated temperature range. Avoid direct contact with water, salt water, or oil. Avoid high humidity where condensation may occur. Avoid exposure to toxic gases (HS, HSO, HNO, Cl, NH), ozone, radiation, UV rays, excessive vibration, or shock.
• Electrical Precautions: Avoid touching terminals due to potential electric shock. The aluminum case is not insulated. Avoid short-circuiting terminals with conductive materials or liquids.

Emergency Procedures

• Pressure Relief Vent Operation: Immediately turn off equipment and disconnect from power source. Avoid contact with escaping electrolyte gas (can exceed 100C). In case of eye contact, flush with water. If ingested, gargle with water. If skin contact, wash with soap and water.

Long Term Storage

Leakage current increases with long storage times due to aluminum oxide film deterioration. Recondition by applying rated voltage in series with a 1000 current limiting resistor for 30 minutes. If the product date code is over eighteen months, return for confirmation.

Capacitor Disposal

Incinerate after crushing or puncturing the can wall to prevent explosion. Incinerate at high temperatures to prevent release of toxic gases. Dispose of as solid waste. Follow local laws for specific disposal requirements.
