When there is a need for high power ratings and high capacitance values, Aluminum Electrolytic Capacitors offer a compact alternative. They provide a smaller form factor while still delivering the required performance.
We offer a range of aluminum electrolytic capacitor body styles to suit different needs. Our options include SMD (Surface Mount Device), radial, and snap-in configurations. For SMD capacitors, we provide variations such as low ESR (Equivalent Series Resistance) and long-life versions. The radial series capacitors excel in high frequency, high ripple, long life, and low impedance applications. Choose the appropriate body style that aligns with your specific requirements and enjoy the benefits of our versatile aluminum electrolytic capacitors.

1. Capacitor which is suitable for power supply circuit by small size, high reliability and long life
2. Lineup of the surface mount and the radial lead type

Electrolytic capacitors are commonly utilized as leaded components, finding their place in a wide range of applications, from power supplies to audio systems that accommodate leaded devices. In situations where high power ratings and high capacitance values are required, Aluminum Electrolytic Capacitors offer a compact capacitor solution. RG Allen specializes in providing aluminum capacitors suitable for demanding applications such as automotive, medical, alternative energy, and more. Count on RG Allen to deliver reliable aluminum capacitors that meet the rigorous demands of these industries.

General Information For Application
The following cautions must be observed when using electrolytic capacitors
1. Polarity:
DC electrolytic capacitors are polarized. If used in reverse polarity, the circuit life may be damaged.
For usage on circuits whose polarity is occasionally reversed or whose polarity is unknown, use non-polar
capacitors.
2. Operating Voltage:
Do not apply a voltage exceeding the capacitor’s rated voltage. Otherwise, the capacitors may be damaged
as leakage current increases.
3. Ripple Current:
The ripple current on the capacitors should be at or below permissible level. Do not allow the current to
pass the capacitors in excess of the specified ripple current.
4. Operating Temperature:
The capacitors should not be used in other than the guaranteed temperature range. Usage at room temperature
will ensure long life.
5. Leakage Current:
The leakage current shall be within specified levels. When capacitors are at a lower voltage, the actual leakage
current will be reduced proportionately.
6. Safety Vent:
Case diameters of 6.3mm and larger for Radial types are designed with case venting, and case diameters
of 8mm and larger for Axial types are designed with safety vent on rubber bung.
7. Soldering:
(A) Be careful of temperature and time when soldering. Dip of flow soldering of the capacitors should be
limited to less than 260°C and 10 seconds.
(B) High levels of humidity will affect the solderability of lead wire and terminals. High temperature will
reduce long term operating life.
(C) Following defective soldering affect the internal characteristics, such as increasing leakage current, short
circuit, broken or wound of lead wires, and leaking electrolyte.
(1.) Parts slant to the board after soldering.
(2.) Leads are greatly bent after soldering.
(3.) Lead space on board differs from the original.
Additional Instructions:
1. After removing capacitors from long-duration storage, aging should be conducted at the rated working voltage
before application, due to increase leakage and decrease of voltage.
2. The electrolytic capacitor is not suitable for circuits in which charge and discharge are frequently repeated,
otherwise the capacitance value may drop, or the capacitor may be damaged.
3. Do not apply excessive force to the lead wires or terminals, otherwise they may be broken or their connections
with the internal elements may be affected.
4. Capacitors will be affected adversely by some solvents. Before using any solvents, please consult with RGA
engineers.
5. Any change and modification on case size and other standard specifications in this catalog may be adopted
without notice.
