Product Overview

The SAMXON KM Series Aluminum Electrolytic Capacitors are polar, foil-type capacitors designed for use in electronic equipment. These capacitors meet IEC60384 standards and are constructed with a tinned CP wire lead, aluminum wire terminal, and are impregnated with electrolyte, enclosed in an aluminum case and sealed with end seal rubber and a vinyl sleeve. They are suitable for applications requiring reliable performance across a wide temperature range (-40C to 105C).

Application Guidelines

1. Circuit Design

• Operating Temperature and Frequency: Electrical parameters vary with temperature and frequency. Higher temperatures increase leakage current and capacitance while decreasing ESR. Lower temperatures decrease leakage current and capacitance while increasing ESR. Higher frequencies decrease capacitance and impedance while increasing tan. Lower frequencies increase ESR, potentially causing heat rise from ripple current.
• Operating Temperature and Life Expectancy: Refer to the file: Life calculation of aluminum electrolytic capacitor.
• Common Application Conditions to Avoid: Reverse voltage, repeating charge/discharge applications, over voltage, and exceeding maximum ripple current can cause rapid deterioration, heating, gas generation, and electrolyte leakage.
• Using Two or More Capacitors in Series or Parallel: Parallel connections may cause ripple current imbalance. Series connections may cause voltage imbalance due to leakage current differences; shunt resistors are recommended.
• Capacitor Mounting Considerations: Avoid wiring patterns under capacitors on double-sided boards. Ensure proper hole spacing to avoid lead stress. Provide clearance for pressure relief vents (2mm for 6.3-16mm, 3mm for 18-35mm, 5mm for 40mm+). Seal mounted vents require a hole in the circuit board. Avoid high voltage/current wiring above vents. Avoid circuit board patterns under the capacitor. For screw terminals, do not orient with the terminal side facing down and tighten within specified torque.
• Electrical Isolation: Ensure complete isolation between cathode and case (except axially leaded B types), anode terminal and other paths, and extra mounting terminals and other terminals.
• Product Endurance: Sample is the standard.
• Load or Shelf Life Test: Collect date code within 6 months products for sampling.
• Capacitor Sleeve: The sleeve is for marking and identification, not electrical insulation. It may be damaged by solvents like toluene or xylene at high temperatures.

CAUTION! Always consider safety. Plan for worst-case failure modes. Provide protection circuits and design redundant circuits.

2. Capacitor Handling Techniques

• Considerations Before Using: Capacitors have finite life; do not reuse from used equipment. Transient recovery voltage may occur and can be discharged with a 1k resistor. Long storage may increase leakage current, correctable by applying rated voltage with a 1k resistor. Avoid using dropped, dented, or crushed capacitors.
• Capacitor Insertion: Verify capacitance, rated voltage, and polarity. Ensure correct hole spacing to avoid terminal stress. Prevent auto-insertion equipment from stressing leads at the seal.
• Manual Soldering: Observe temperature and time specifications (do not exceed 400 for 3s). Avoid stress on lead wires during forming. Avoid excessive stress during reinsertion. Do not touch the capacitor body with the soldering iron.
• Flow Soldering: Do not immerse the capacitor body in the solder bath. Observe proper soldering conditions. Prevent other components from touching the capacitor during soldering.
• Other Soldering Considerations: Avoid rapid temperature rises during preheat and resin bonding. For heat curing, do not exceed 150 for 2 minutes.
• Capacitor Handling after Solder: Avoid movement after soldering. Do not use the capacitor as a handle. Avoid striking the capacitor after assembly.
• Circuit Board Cleaning: Boards can be cleaned using suitable solvents for up to 5 minutes at 60. Rinse and dry thoroughly. Avoid ozone-depleting agents. Avoid halogenated, alkali, 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.

3. Precautions for using capacitors

• Environmental Conditions: Do not store or use outside rated temperature range, in contact with water/salt water/oil, high humidity, toxic gases (H2S, H2SO4, HNO3, Cl2, NH3), ozone, radiation, UV rays, or exceeding vibration/shock requirements.
• 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.

4. Emergency Procedures

• If the pressure relief vent operates, immediately turn off equipment and disconnect power. Avoid contact with escaping electrolyte gas (>100). In case of eye contact, flush with water. If ingested, gargle with water. If on skin, wash with soap and water.

5. Long Term Storage

• Leakage current increases with storage time. Recondition capacitors stored for over one year by applying rated voltage in series with a 1000 resistor for 30 minutes. If the date code is over eighteen months, return for confirmation.
• Environmental Conditions: Same as section 3.1.

6. Capacitor Disposal

• Incinerate after crushing or puncturing the can wall. Incinerate at high temperatures to prevent toxic gas release. Dispose of as solid waste. Follow local laws.
