Application Guidelines

Circuit Design Considerations:

• Ensure operating environment and conditions are within catalog specifications.
• Operating temperature and ripple current must not exceed specified limits.
• Select capacitors that meet the required life expectancy.
• Aluminum electrolytic capacitors are polarized; avoid reverse or AC voltage. Use non-polar types for circuits with potential reversed polarity.
• Avoid circuits requiring rapid and frequent charge/discharge; use special design capacitors for such applications.
• Do not apply excess voltage; ensure peak voltage (DC + ripple) does not exceed rated voltage. Use balancing resistors for series connections.
• Outer sleeve is not guaranteed as an electrical insulator. Contact sales for applications requiring special insulation.
• Do not connect blank terminals of snap-in type products to other circuits to avoid short circuits.
• Avoid exposure to water, brine, oil, toxic gases, ozone, UV, radiation, severe vibration, or physical shock exceeding specifications.
• Ensure PC board hole spacing matches lead spacing.
• Keep circuit patterns or wires away from the capacitor safety vent. Maintain specified clearance above the vent.
• For snap-in type capacitors with end seal side down, make a hole on the PC board for gas release.
• For screw terminal capacitors, avoid end seal side down mounting. For horizontal mounting, the positive terminal must be in the upper position.
• Locate circuit patterns away from the capacitor end seal to prevent pattern corrosion or short circuits due to electrolyte leakage.
• Avoid placing heat-generating components near aluminum capacitors or on the reverse side of the PC board under the capacitor.
• Consider temperature and frequency variations on electrical characteristics during circuit design.
• On double-sided PC boards, do not place capacitors over circuit patterns or unused holes.
• Ensure terminal screw torque is within specified values.
• When paralleling capacitors, consider current balance.

Mounting Precautions:

• Do not reuse a capacitor after it has been assembled and powered.
• Discharge capacitors using a 1k resistor before handling.
• Leakage current may increase after storage exceeding 6 months; perform voltage treatment if necessary.
• Confirm ratings and polarity before installation.
• Do not drop capacitors or use dropped ones.
• Be careful not to deform the capacitor during installation.
• Ensure lead spacing matches PC board hole spacing.
• Snap-in type capacitors should be installed tightly to the PC board.
• Avoid excessive clinch force during automatic insertion.
• Protect capacitors from mechanical shock during automated processes.
• Soldering conditions must be within SAMXON specifications for both Pb/Sn and Pb-free types.
• Do not tilt, lay down, or twist the capacitor body after soldering.
• Do not carry PC boards by grasping soldered capacitors.
• Prevent anything from touching the capacitor after soldering. Avoid radiated heat from other components affecting the capacitor.
• Do not clean capacitors with halogenated cleaning agents.
• When fixing or coating, avoid halogen-containing ingredients. Remove flux and contamination from the end seal gap and dry thoroughly before coating. Apply coating partially, not all around the capacitor body.
• Consult sales for compatibility of coating material curing conditions.
• Do not install screw terminal capacitors with the end seal side down. For horizontal mounting, the positive terminal must be in the upper position.

Storage:

• Store capacitors at 5C to 35C, humidity less than 75% RH, out of direct sunlight.
• Capacitors stored for over one year may require voltage aging treatment to reform the oxide dielectric.

Disposal:

• Dispose of capacitors as industrial waste through professional waste disposal specialists.

Printed Circuit Board Cleaning:

• Halogen type organic solvents can permeate capacitors and cause corrosion due to chlorine ions.
• Recommended alternatives include water or alcohol-based cleaning agents, pre-cleaning PC boards, or using capacitors with epoxy end seals.
• Solvent penetration can occur through clearances between the rubber and aluminum case, rubber and lead wires, or permeation through the rubber end seal. Tight sealing and solvent-resistant rubber are crucial.

Basic Electrical Characteristics:

• Capacitance: Measured as AC capacitance at 120Hz, 0.5Vrms AC voltage, with 1.5-2.0V DC bias. Capacitance decreases with increasing frequency and decreasing temperature.
• Tan (Dissipation Factor): Ratio of resistive to capacitive reactance. Increases with frequency and decreases with temperature.
• ESR (Equivalent Series Resistance): Comprises resistance from oxide layer, electrolyte, separator, foil length, etc. Increases as temperature decreases. Decreases with increasing frequency, stabilizing at a value mainly determined by electrolyte/separator resistance.
• Impedance (Z): Opposes AC current. Predominantly capacitive reactance at low frequencies, ESR at mid-frequencies, and inductive reactance at high frequencies. Impedance is temperature-dependent due to electrolyte resistivity changes.
• Leakage Current: Small DC current flowing to reform the oxide layer. Higher leakage at initial voltage application, stabilizing over time. Increases with temperature and voltage. Measured at 20C with rated voltage through a 1,000 series resistor.
